A new system and method is described, utilizing a scheduler based on a transmission power consumption calculation and prioritizing algorithm. The system utilizes the (APSD) protocol specified in the 802.11e draft for saving power in wireless local area networks. The system comprises an access point having a priority queue, one or more stations, an APSD frame comprising an association ID for identifying one of the stations and a scheduled wake-up time for the identified station. An algorithm is employed for calculating the total transmission power consumption of downlink data for the stations. The AP originates and transmits to the one or more stations the APSD frame of the scheduled activation delay time. The current data to be transmitted to each station is accessed by the algorithm to determine the total transmission power consumption to each station. A priority queue in the AP is ordered from the lowest to the highest receiving power consumption, assigning the highest priority to the lowest power consumption transmission to minimize total power consumption to the PS stations in the AP queue.

A terminal determines a target value of stream data to be stored in its buffer in relation to its buffer capacity and the transmission capacity of the network. Also, the terminal arbitrarily determines a delay time from when the terminal writes a head data of the stream data to the buffer to when the terminal reads the data to start playback in a range not exceeding a value obtained by dividing the buffer capacity by the transmission capacity. The target value and the delay time are then both notified to a server. Based on those notified values, the server controls the transmission speed so that the buffer occupancy of the terminal changes in the vicinity of the target value without exceeding the target value.

There is provided herein an electronic patient monitor that is suitable for use with a variety of different sensors and which automatically configures itself depending on the sensor that is used and/or the environment in which the electronic monitor is placed. In a first preferred embodiment, the electronic monitor determines whether it is being used on a bed or a chair by sensing whether or not a nurse call connector is present. If such a connector is plugged into the monitor, the unit will assume that it is being used with a sensor that has been placed on a bed and will configure its internal parameters appropriately. Such configuration would include changing a delay time to provide for longer delays before sounding an alarm than would be used with a chair monitor.

A method for controlling errors in a wireless link layer using a simultaneous multiple copy scheme and an adaptive forward error correction (FEC) scheme in a wideband wireless communication is provided. The method for controlling errors in a link layer in wideband wireless communication using an automatic repeat request (ARQ) scheme, in which a wideband wireless channel is used for communication between a first node and a second node, includes the steps of (a) estimating the error ratio of a forward (a direction in which a cell is transmitted from the first node to the second node) channel using the state of a backward (a direction in which a cell is transmitted from the second node to the first node) channel, and transmitting a cell, in which a forward error correction (FEC) code having an encoding ratio that varies depending on the estimated error ratio is included in a protocol data unit (PDU) of a wireless link layer, through the forward channel and (b) re-transmitting the copy of a cell transmitted in the step (a), when feedback information that indicates that an error exists in the cell transmitted in the step (a) is received through the backward channel. It is possible to reduce the number of times of re-transmission by improving the probability of correcting forward errors using more error controlling bits as the state of the channel is worse and to minimize the waste of resources using less error controlling bits as the state of the channel is better, to thus obtain the optimal performance and guarantee the minimum delay time.

An apparatus and method for advancing a receiver into registered relationship with a moving image-bearing member. A motor is provided that is responsive to motor drive pulses. A drive member engages the receiver, and a drive coupling connects the drive member and the motor. An encoder generates encoder pulses that correspond with movement of the image-bearing member. A pulse generator generates motor drive pulses in response to the encoder pulses to accelerate the receiver to a speed approximately equal to the speed of the image-bearing member speed. A timer determines an amount of delay time between detection of the receiver by an in-track sensor and the beginning of a subsequent movement of the motor. A delay mechanism delays the acceleration of the receiver to the image-bearing member speed by the amount of delay time.

A sound measuring apparatus for measuring a sound-arrival delay time from a speaker to a microphone on the basis of a result obtained by outputting a test signal from the speaker and picking up the test signal using the microphone includes the following elements. A control unit performs control so that the test signal is expanded in a time axis and is then output from the speaker. A delay time measuring unit measures an expansion-based measured delay time on the basis of a delay time that is measured on the basis of a time difference between the test signal expanded in the time axis and output from the speaker and a signal obtained from the microphone by picking up the output expanded test signal, and obtains the sound-arrival delay time as the expansion-based measured delay time.

The invention relates to methods for (re)attaching a UE to a 3GPP access network and for storing bearer context information of a UE upon handover from a 3GPP access network to a non-3GPP access network. Furthermore, the invention relates to 3GPP network nodes, such as mobility management entity, serving gateway and packed data gateway, and a UE that are specially adapted to perform these methods. In order to decrease of the delay time during (re)attachment of a UE to a 3GPP access network, the invention proposes to maintain context information on data bearer(s) of a UE within the 3GPP access network and the UE, while the UE is not attached to the 3GPP access network, so that data bearer context information for this UE is available and can be used for the (re)activation of data bearer(s) once the UE is attaching to the 3GPP access network again.

A multi-channel audio system is constituted using at least one line array speaker unit, in which plural speakers are arrayed in line, wherein the same audio signal is supplied with a prescribed delay time to each of the speakers, thus forming plural sound beams. The plural sound beams are reflected on a wall surface and a ceiling of a room so as to form plural virtual sound sources surrounding a listening position, and emission directions and intensities of the sound beams are controlled so as to localize a phantom at a prescribed position based on the plural virtual sound sources. By appropriately arranging plural line array speaker units horizontally, vertically, and slantingly in such a way that each line array speaker unit forms sound beams distributed and spread in a sectorial form, it is possible to realize a surround audio system having a high degree of freedom with regard to setup positions for forming virtual sound sources.

A multi-view video signal is encoded. The multi-view video signal includes picture signals corresponding to different viewpoints respectively. One among the viewpoints is designated as a base viewpoint. The base viewpoint corresponds to a picture signal which is encoded without referring to at least one picture signal corresponding to one of the viewpoints except the base viewpoint. There is determined a desired delay time of the start of decoding a coded signal originating from each of the picture signals corresponding to the viewpoints except the base viewpoint relative to the start of decoding a coded signal originating from the picture signal corresponding to the base viewpoint. Information representing the determined delay time is generated. Then, the generated information is encoded.

A security system including a roam control unit, a plurality of sensors and a user interface device. The main control unit communicates with a remote central monitoring station, when a sensor detects an alarm event. Once the communication signal from the main control unit is successfully transmitted to the central station, a siren is sounded. Thus, the delay time to trigger the siren is dynamic based on the time it takes for successful transmission of an alarm notification to the central station. This dynamic delay accounts for transmission interruptions between the security system, and the central station and allows the location of the main unit and/or the siren from being detected prior to successful, alarm transmission, to the central station.
