Abstract: The invention provides a method for verifying the age of an animal providing meat using volatile profiles that comprises the step of providing a sample of animal meat. The method uses one or more chemical analyzes to obtain a profile of a set of volatile organic compounds from a sample of meat from an animal. The profile is fit to a mathematically discriminating function resulting. The data obtained is analyzed in order to establish a correlation between the age of the animal (tooth development) and volatiles exuded by meat.

Abstract: Techniques are described for use in scanning by a mobile device which is configured to communicate in compliance with regulatory requirements of a regulatory domain based on country information communicated in one or more beacon frames. The mobile device scans a radio frequency (RF) band using passive scan operations on RF channels having passive scan status, where each passive scan operation involves monitoring an RF channel in attempt to decode a beacon frame. When the mobile device successfully decodes, on an RF channel for a passive scan operation, an information frame of a type that is different from a beacon frame, it changes the passive scan status of the RF channel to an active scan status and performs an active scan operation on the RF channel.

Abstract: In one illustrative example, a method in a mobile communication device operating in a wireless local area network (WLAN) involves performing, via a wireless AP of the WLAN, a first authentication procedure with an authentication server for obtaining a first session key and a key lifetime value associated with the first session key; establishing a first secure connection with the wireless AP based on the first session key; setting a timer with an initial value that is less than or equal to the key lifetime value, and running the timer; communicating in a media session over the first secure connection with the wireless AP; and in response to an expiration of the timer during the media session: performing, during the media session, a second authentication procedure with the authentication server for obtaining a second session key; and establishing, during the media session, a second secure connection with the wireless AP using the second session key; and communicating in the media session over the second secure

Abstract: The disclosure relates to a system and a method for reducing power consumption of a communication device. The method has a power save mode controlling a deactivated communication subsystem of the device, where: for a first period, re-activating the subsystem, executing an action relating to a data link layer connection condition for the network, and then de-activating the subsystem; and for a second period, re-activating the subsystem, generating and transmitting a frame to a host in the network, and then de-activating the subsystem. The first period is repeated on a first frequency timed to allow the device to process a beacon signal that is received at an interval of at most every third beacon signal in a succession of beacon signals from the network; and the second period relates to a frequency of transmission of an Address Resolution Protocol request for an Internet Protocol address for the device.

Abstract: A mobile wireless communications device includes a user-visible peripheral, such as a display, and a processor. A reset management block is associated with the processor to manage reset of the device. The processor includes the use of an operating system (OS) which is resettable along with a reset of a state of the user-visible peripheral. The operating system is also resettable without resetting the state of the user-visible peripheral to avoid a user-visible change therein.

Abstract: A system and method are provided for monitoring the quality of a communication session with a first electronic device. Should the communication session degrade, rather than dropping the communication session the user of a second electronic device communicating with the first electronic device is prompted to wait while an attempt is made to improve the quality of the communication session. Similarly if the user of the first electronic device moves out of a coverage area, rather than dropping the communication session the user of the second electronic device communicating with the first electronic device is prompted to wait until a new communication session can be established.

Abstract: A mobile device sends to a message a wireless network. The message indicates a plurality of different protocol types of broadcast messages to be processed as broadcast-to-unicast messages during a low power mode of operation of the mobile device. The protocol type of a given broadcast message is identifiable in a protocol identifier field of the broadcast message. The mobile device maintains its wireless receiver in a powered down state during the low power mode of operation while broadcast messages are broadcasted from the wireless network. For each broadcast message of each said indicated protocol type provided in the message sent to the wireless network, the mobile device monitors to receive via the wireless receiver a unicast message from the wireless network. The mobile device identifies broadcast message information of the broadcast message within the unicast message.

Abstract: In a Wireless Local Area Network (WLAN), roaming from one access point to another by a mobile station without interruption to network service may be facilitated by frequently performing background scans to find neighboring access points while the mobile station is associated to the WLAN. Frequent background scanning, however, depletes battery life. By dynamically adjusting the background scanning interval during the mobile station's association to the WLAN, the mobile station's immediate need for network connectivity performance may be met, while simultaneously prolonging battery life. For example, by using a shorter background scanning interval during a telephone conversation, network connectivity performance may be maintained throughout the call. Longer background scanning intervals may be used during periods when interruptions to network connectivity may be better tolerated.

Abstract: One illustrative method for reducing power consumption in a mobile communication device of a wireless local area network (WLAN) involves the steps of identifying a communication signal quality value between the mobile device and a wireless access point of the WLAN with which the mobile device is currently associated; determining an initial timer value based on a predefined relationship with the communication signal quality value where, as the communication signal quality value decreases, the initial timer value correspondingly decreases; initializing a scan trigger timer with the initial timer value and running the scarf trigger timer; and upon expiration of the scan trigger timer: causing a scanning operation to be performed for identifying one or more wireless access points in a coverage region; and repeating the acts of identifying, determining, initializing and running the scan trigger timer, and causing the scanning operation to be performed.

Abstract: Techniques for use in communicating messages to a mobile device operative in a wireless network are described. A communication network receives a broadcast message which includes a protocol type identifier in a protocol type identifier field. The communication network identifies whether the protocol type of the broadcast message matches one of a plurality of protocol types stored in association with an identification of the mobile device. If the protocol type of the broadcast message matches one of the stored protocol types, then the communication network produces, from the broadcast message, a unicast message which includes information from the broadcast message, and causes the unicast message to be sent to the mobile device in the wireless network.

Abstract: A continuous-time delta-sigma analog-to-digital converter (ADC) is disclosed. The ADC includes a loop filter, a loop quantizer, and a clock-jitter tolerant digital-to-analog converter (DAC). The clock-jitter tolerant DAC includes a dual switched-current (SI) DAC, a switched-capacitor (SC) DAC, an adder, and a switched-capacitor-resistor (SCR) injection circuit. The dual SI DAC provides two identical analog signals from the feedback digital signal of a loop quantizer within the ADC. The SC DAC provides an error-free reference signal from the feedback digital signal. The adder subtracts one of the two analog signals from the error-free reference signal to obtain an inverted jitter-induced error signal. The SCR injection circuit then injects the inverted jitter-induced error signal, delayed by one clock-cycle, in the form of a half-delay return-to-zero exponentially decaying waveform into the loop filter.
