A ventilatory support system which controls the flow of breathing gas to a patient based on the physiological requirements of the patient is disclosed. Gas pressure in the trachea of the patient is measured, and the delivery of breathing gas to the patient is controlled based on the sensed gas pressure. Depending on the physiological needs of the patient, a tracheal gas pressure limit and a breathing gas flow rate value are established. When the tracheal gas pressure limit is reached, the flow of breathing gas is reduced or terminated. The flow of breathing gas is resumed, for example, after a delay period, or after the tracheal gas pressure falls to a predetermined level.

A method is disclosed for improving head position accuracy in a disk drive during track following of concentric data storage tracks through real-time identification of external vibration and monitoring of write-unsafe (WUS) occurrences. In the method, after a seek operation to a predetermined data storage track, the track is followed using a servo control loop having a nominal gain and responsive to a position error signal (PES). After waiting a vibration detection delay period, occurrences of the PES exceeding a WUS limit are counted generating a WUS limit exception count. Also, a property of a variance is determined from spectral power values generated from the PES during track following. If the WUS limit exception count exceeds a first threshold, and if the property of the variance exceeds a second threshold, the nominal gain is increased to a vibration gain within a frequency band, to attenuate the effect of external vibration.

An automated banking machine system and method includes ATMs which accept checks and dispense cash to users. The ATMs are operated to acquire image and magnetic data from deposited checks to determine the authority of a user to receive cash for such checks. The authority of the user is determined based on the user being associated in a data store with the maker of the check. The check cannot exceed certain programmed thresholds or be presented earlier than the expiration of a delay period from when a prior check from the same maker is presented. In exchange for acceptable checks cash is dispensed to the user from the ATM in exchange for the deposited check.

A computer implemented method for automatic presentation of delayed video. During normal operation real-time video feed is sent to a digital screen for presentation and is also sent to memory for storage. When a delay trigger is issued, the system either freezes the frame presented in that instance or stores a time indicator. The system then monitors delay time and, when the delay time is reached, the system starts fetching frames from the memory, starting either from the frame immediately following the frozen frame or from the frame that was stored at the time indicator, and sends these frames to the digital screen for presentation. The system then monitors delay period and, when the delay period arrive, the system reverts to normal mode wherein real-time video feed is sent to a digital screen for presentation and is also sent to memory for storage.

A device and a method for managing access requests, the method includes: (i) receiving, from a master component coupled to a master bus, multiple access requests to access a slave component over a pipelined slave bus; acknowledging a received access request if: (a) at least an inter-access request delay period lapsed from a last acknowledgement of an access request; (b) an amount of pending acknowledged access requests is below a threshold; wherein the threshold is determined in response to a pipeline depth of the pipelined slave bus; (c) the received access request is valid; wherein a validity of an access request is responsive to a reception of an access request cancellation request; and (ii) providing information from the slave component, in response to at least one acknowledged access request.

A system and a method transfer multiple data channels between a server and a terminal via a stream session over a network. The system and the method utilize a bitstream switching, a fast buffer filling and/or a fast playback start to facilitate a switch from a first data channel and a second data channel. The first data channel and/or the second data channel is delivered to and/or is transferred to the terminal from the server over the network via a streaming session. The server transfers second data of the second data channel to the terminal via one or more tracks which are encoded at more than one bitrate and/or are configured in one or more configurations. The terminal requests a change between the first track and/or the second track without terminating the stream session for the first data channel between the terminal and the server. As a result, the system and/or the method minimizes the delay period of time between requesting the switch to the second data channel and displaying the second data channel.

The invention concerns a method and apparatus for performing packet loss or Frame Erasure Concealment (FEC) for a speech coder that does not have a built-in or standard FEC process. A receiver with a decoder receives encoded frames of compressed speech information transmitted from an encoder. A lost frame detector at the receiver determines if an encoded frame has been lost or corrupted in transmission, or erased. If the encoded frame is not erased, the encoded frame is decoded by a decoder and a temporary memory is updated with the decoder's output. A predetermined delay period is applied and the audio frame is then output. If the lost frame detector determines that the encoded frame is erased, a FEC module applies a frame concealment process to the signal. The FEC processing produces natural sounding synthetic speech for the erased frames.

A programmable, customizable system, method, and apparatus for attracting and stimulating aquatic animals are disclosed. The present invention provides for the underwater playback of digitally prerecorded “signature” sounds of prey, and of prey being attacked and eaten, in order to attract fish and other species and stimulate them to strike and feed more aggressively. Playback is achieved by selecting any of a plurality of signature sound recordings stored on a memory device which is located and controlled above water. One sound, all sounds, or a selected sequence of sounds may be selected from the memory device to be played underwater. Underwater playback is achieved by use of a submersible transducer device which may function as both a speaker and a hydrophone. Underwater playback may be customized and controlled above water by providing a number of customized operational modes. For example, a user may select a sound recording to be repeatedly played in a loop, with each iteration separated by a delay period, the length of which is selected by the user. In addition, the user may select a plurality of different sound recordings, and specify the sequence and volume at which they are played underwater, as well as a delay period between each recording. The user may also select all sound recordings to be played at a selected volume level, and the user may further specify a delay period between each recording. Furthermore, the user may select sound recordings to be played underwater at varying volume levels according to selections made by the user.

The preferred dry system can be further configured such that each and every sprinkler in the system has a fluid delivery delay period equal to or less than the maximum fluid delivery delay period.

A method and a video camera for recording an event initiated video sequence includes storing captured video frames in a video buffer, detecting a first event, and in response, initiating a video sequence recording session for recording of a video sequence in a non-volatile memory. Pre-event video frames and post-event video frames related to the first event are recorded, where the post-event time period starts at the detection of the first event. A first event delay time period is started in response to the expiration of the post-event time period. The video sequence recording session is closed if a delay period expires and no other event process is in progress.

A high-performance dynamic flip-flop circuit implementation. The dynamic flip-flop circuit comprises an "implicit" one-shot to generate a delayed clock output (319). The flip-flop comprises a delay block (317) coupled to a clock input (305). The flip-flop may be a D-type flip-flop. In a positive-edge-triggered embodiment of the flip-flop, a falling edge (440) of the delayed clock output (319) follows a rising edge (444) of a clock signal after a delay period (448). The flip-flop clocks in new data at a data input (305) in response to the clock input (310) during this delay period (448). Data is held in a storage block (360). The flip-flop has extremely good transient characteristics, especially set-up and clock-to-output times. The flip-flop consumes no static power.

An output voltage error detection unit outputs an auxiliary winding voltage generated across an auxiliary winding having the same number of turns as a secondary winding a certain period after a secondary conduction period starts. A correction amount calculation unit calculates a secondary voltage drop caused by a secondary current flowing in the conduction period based on a primary current flowing when the conduction period starts and outputs a calculation result as a correction amount. A reference voltage generation unit generates a reference voltage by adding the correction amount to the output voltage. A control unit generates a feedback signal to minimize the error between the auxiliary winding voltage obtained after a certain delay period and the reference voltage. A PWM signal generation unit controls a PWM signal based on the feedback signal, adjusts switching of the switching element, and maintains the output voltage at a constant level.
