A synchronization mechanism embeds synchronization triggers into a television signal or stream at regular intervals. The triggers include an accurate representation of the time in which the triggers were embedded. A receiving device decodes the triggers and synchronizes its internal timer based on the triggers. In this regard, the receiving device obtains a reference time from the internal timer and computes an offset between the reference time and the trigger time. The computed offset is then applied to the reference time. With the receipt of each new trigger, the application compares the trigger time to a new reference time with the most recently computed offset value applied. If there is any variance between these two values, the application creates a new smoothed offset.

A process for measuring the absorption spectrum of a target analyte using a cavity ring down spectrometer, comprising the steps of: i) tuning the spectrometer laser so that the light transmitted from the laser into the spectrometer optical cavity is varied over a wavelength interval which encompasses both the absorption wavelength of a spectral feature of the target analyte and a plurality of the free spectral ranges of the optical cavity; ii) triggering a plurality of ringdown events; iii) for each ringdown event, recording the decay time constant and the trigger time at which the light into the cavity is shut off; iv) organizing the decay time constants, light wavelengths and trigger times as a function of trigger time; v) ordering said light wavelengths by increasing value and placing groups of wavelengths into individual bins; vi) computing the average wavelength of each bin group; vii) grouping the decay time constants and trigger times into bins that parallel said wavelength bins, with the decay time constants in each of said parallel bin being arranged by increasing trigger time; viii) computing the average decay time for each decay time bin and using this decay time average, together with the average wavelength from the parallel wavelength bin, to compute the optical loss for the target analyte at said average wavelength.

The disclosed system and methods include a power saving scheduler that maintains timed events in an event table. Each timed event has an associated tolerance period within which the event should begin execution following a trigger, and a timestamp indicating a scheduled execution time for the event. When a device is in a low-power sleep mode, a trigger may wake up the device to a wake state. The power scheduler then accesses the event table of upcoming timed events, and reorders the event table from the event having the shortest tolerance period to the event having the longest tolerance period. Each event for which the timestamp is within the tolerance period as measured from the trigger time is executed. After a plurality of such events are executed, the device may return to the sleep mode.

A system and method in which a Radio Link Failure, RLF, report from a User Equipment, UE, provides system time-based timestamps to enable a source node to correctly analyze the real cause of an RLF associated with a handover. The timestamps are provided for the latest fulfillment of each event-specific entering condition associated with a handover-triggering event and for the occurrence of the RLF. The recorded timestamps are sent as part of RLF-reporting information to be forwarded to the source node to assist the source node in adjusting event-specific threshold(s) as well as other non-threshold related handover parameters such as the Time To Trigger, TTT, period, the time delay between a UE's transmission of its Measurement Report and the source node's transmission of the handover command, and the like, to reduce similar RLFs in the future. The generation of timestamps does not waste the UE's processing resources or battery power.

Calendar and scheduling applications organize and display user events and provide event reminders. A method of triggering a reminder includes accessing a reminder which describes an event. An individual associated with the event, other than the user, is identified. A future time is predicted when the user will be within proximity of the individual. A time to trigger the reminder for presentation to the user is determined, such that the time to trigger the reminder occurs in advance of the predicted future time when the user will be within proximity of the individual. Based on a determination that the time for triggering the reminder has occurred, the reminder is triggered to be presented to the user.

An electronic hand hygiene compliance system and award indicator that provides realtime reporting of the percent number of hand hygiene events against a programmed target number of hand hygiene events for a given functional area over a given period of time, yielding hand hygiene compliance. The system keeps up to date compliance for an established group interval until the data is written over by compliance data for the same group interval the following day. In addition, a random hand hygiene event can be identified for a given functional area during a given period of time to trigger an alarm for encouraging hand hygiene activity for a given dispenser or group of dispensers.

Methods and apparatus for mitigating in-device interference are described. The methods may include an in-device interference event (e.g. an interference situation), and the processing of events may depend on the priority of the technologies. A handover to another frequency or radio access technology (RAT) may occur in case a co-existing technology may be activated. The network may signal to the device a list of frequencies or RATs that it may be allowed to measure and handoff to. A network may provide a scaling value that the device may use to speed up reaction to the interference. The device may apply a scaling factor to an "out of synch' counter and/or the radio link failure (RLF) timer used for the RLF procedure. The device may apply different scaling factors for the measurements and time to trigger events. The device may trigger a report to the network requesting gaps for an alternate RAT.

The invention discloses a processing method and a processing device of a timer. The processing method of the timer includes: dividing trigger time of timer events into a plurality of time periods, wherein each time period corresponds to a hash value; inserting timer events with the trigger time at an identical time period into an identical chain table; and mapping the timer events of various chain tables into a hash table, wherein each timer event correspondingly stores a hash value and identification of the chain table where the timer event is located into the hash table. The processing method and the processing device of the timer solve the problem that a timer in the prior art is relatively large in system overhead due to the processing mode, and achieve the technical effect that the system overhead of processing a timer event is reduced.

The invention discloses a laser ranging method. The laser ranging method includes that an initial threshold value is set by an MCU (microprogrammed control unit), and a first pulse is emitted to trigger a time-to-digital converter to start timing; a second pulse is emitted after a certain time delay to trigger an emitting module to emit laser, and simultaneously, a receiving module is opened to receive an echo signal of the laser; when the echo signal received by the receiving module is larger than the initial threshold value, a high-speed comparator outputs a measurement timing stop pulse to the time-to-digital converter, the MCU reads time difference of the measured earlier pulse and the measured later pulse of the time-to-digital converter so as to compute the measurement distance and drive an LCD (liquid crystal display) to display a measurement result in real time, if the echo signal received by the receiving module is not larger than the initial threshold value, the MCU sets the threshold value to a lower threshold value, the time-to-digital converter and the receiving module are initiated to enter a ranging procedure with the low threshold, when an echo signal is larger than the low threshold value, the high-speed comparator outputs a measurement timing stop pulse to the time-to-digital converter, and if the echo signal is not larger than the low threshold value, the ranging procedure is terminated.

A self-contained head set based sleep or fatigue alarm for a driver of a vehicle contains a set of arms extending from the alarm housing around the driver's head to the area under the driver's lower jaw. Involuntary relaxation of the driver's lower jaw causes rotation of the arms which in turn urges the movable contact against the stationary contact and therefore leads to the completion of the electrical circuit. After a predetermined delay, a buzzer or vibrator is activated to awaken the driver. In another embodiment, two relaxation motions, jaw lowering and head tilting, are used at the same time to trigger the alarm. In a third embodiment, either one of these two relaxation motions is used to trigger the alarm independently thus increasing the sensitivity of the alarm.

A terminal starts a first timer for detecting an RLF (Radio Link Failure) when signal strength of a serving base station is lower than a reference value. The terminal triggers a handover without a TTT (Time to Trigger) for handover when signal strength of a target base station is greater than the signal strength of the serving base station by a first offset or more while the first timer is running. The terminal transmits a measurement report message regarding the signal strength of the target base station to the serving base station when a handover is triggered.

The present invention provides a method of determining handoff parameters. One embodiment of the method includes determining values of a hysteresis for a handoff from a serving cell, one or more pairwise offset values for hand off between the serving cell and one or more neighbor cells, and one or more times-to-trigger (TTTs) for hand off between the serving cell and the neighbor cell(s). The values may be determined So that hand off is triggered beyond a first distance from the serving cell selected to avoid ping-ponging and within a second distance from the serving cell selected so that a mobile unit moving at a selected velocity does not travel beyond a third distance within the TTT.

A data management method for a long record length memory that is used for data acquisition writes data samples into an initial circular buffer within the memory having a size equal to a pre-trigger time. When a first trigger event occurs, the data samples are then written into a linear region after the circular buffer within the memory. The data sample acquisition in the linear region continues until a post-trigger and new pre-trigger time have elapsed after a last trigger event, at which point the acquisition terminates and the new pre-trigger time becomes a new circular buffer for a next trigger event. In this way all trigger events are captured with associated pre-trigger and post-trigger data.

An apparatus and method for retracting an awning. A sensor detects an awning acceleration caused by wind impacting the awning, and generates a signal having an amplitude corresponding thereto. When the signal exceeds a certain threshold, the awning is retracted. The signal's amplitude may be converted into a frequency, and the frequency compared to the threshold. The signal typically must exceed the threshold for a set period of time to trigger awning retraction. A second threshold may dictate a maximum instantaneous or peak acceleration; when the signal exceeds this second threshold, regardless of the duration during which the second threshold is exceeded, the awning is retracted.
