Abstract: A system and method tracks a user's eye for a data trigger arrangement. The method includes obtaining first image data within a first vision field of a first data capturing sensor. The method includes determining a first area viewed by a user's eye as a function of the first image data. The method includes obtaining second image data within a second vision field of a second sensor. The method includes determining a second area captured within the second field of vision as a function of the second image data. The method includes determining disposition data of the first area within the second area. When a trigger command is captured, the method includes data capturing a machine readable representation of data (MRRoD) using the second sensor as a function of the disposition data.

Abstract: Described is a system and method for charging a battery. The system includes a processor powered by a battery; and a controller determining a remaining battery charge of the battery. The controller sets a first charge current to recharge the battery when the remaining battery charge is insufficient to operate the processor. The controller wakes the processor when the battery has been recharged so that the remaining battery capacity is sufficient to operate the processor. The processor negotiates for a second charge current to recharge the battery. The controller sets the second charge current when the processor successfully negotiated.

Abstract: A method and apparatus are provided by which a mobile device performs power management functions. According to some embodiments, a controller detects a pattern of push events on at least a button of the mobile device and determines whether the detected pattern matches the stored pattern or not. The controller upon detecting that the detected pattern matches the stored patterns, transmits a signal to a processor of the mobile device to perform a predetermined power management function on the mobile device when the detected pattern matches the stored pattern wherein the predetermined function is associated with the stored pattern.

Abstract: Audible crosstalk can be mitigated in a low-cost three-wire device having audio capability and/or voice applications. In some embodiments, a voltage can be introduced in a microphone power supply that is approximately the same as a measured noise voltage and the resulting voltage appearing at a microphone output can be optimized to mitigate the noise voltage and, thus, the presence of crosstalk. In some embodiments, a microphone within a circuit can be isolated to mitigate crosstalk by introducing current into a circuit that is approximately the same as a measured current, but having a flow in an opposite direction.

Abstract: Described is a method for suspending operation of a mobile unit. Data, settings, an operating system state, and/or at least one application state of a mobile unit is saved to a non-volatile memory. At least one component of the mobile device is deactivated. The mobile unit is placed in a suspend mode.

Abstract: Systems and methods for an electronic shopping system are provided. The electronic shopping system includes a shopping cart tablet and a mobile terminal that can be hand-held and/or coupled to any suitable product carrying device. The shopping cart tablet includes a display to display information relating to ordinary operation of the tablet and/or a mobile terminal. The shopping cart tablet also includes a charge cradle for charging the mobile terminal. The mobile terminal includes a window in which a bar code reader is able to read a bar code label and a display for displaying product information. A shopping cart handle is also included in the electronic shopping system for supporting the shopping cart tablet and mobile terminal. A storage rack that is operable to store and/or charge shopping cart tablets and/or mobile terminals is also included in the electronic shopping system.

Abstract: Signals received by an electronic article surveillance system are processed digitally to ascertain the variation in magnitude of successive signals and to prevent the actuation of an alarm when the variation exceeds a predetermined amount; and signals whose frequency components have been phase shifted from a filtering operation are restored by passing them into a signal delay circuit, tapping the delay circuit at several points therealong into associated signal channels selectively amplifying or attenuating the signal in each channel and combining the signals in each channel.

Abstract: First and second ISDN modems are disposed at a subscriber location and telephone system central office and are arranged to operate in a normal mode, and in a bypass mode upon power failure at the subscriber location. The modems are coupled through the telephone lines via interface transformers having centertaps. The centertap at the subscriber location is split and coupled to a sealing current source and that at the central office is coupled to a sealing current detector and ground. Sealing current flows between the respective transformers during normal operation. A drop in sealing current due to subscriber power failure is sensed at the central office, causing local logic to bypass the central office interface transformer and to couple the central office voice switch directly to the telephone lines. Loop current detectors at the subscriber location and at the central office determine whether the subscriber location voice telephone device is on-hook.
