Abstract: A finger biometric sensor assembly may include a finger biometric sensor integrated circuit (IC) die having a finger sensing area and a cover layer aligned with the finger sensing area. The finger biometric sensor may also include a direct bonding interface between the finger biometric sensor and the cover layer.

Abstract: An electronic device may include a finger biometric sensor and a processor being switchable between, a user-interface locked mode and a user-interface unlocked mode. The processor may cooperate with the finger biometric sensor to acquire spoof detection data based upon an object being placed adjacent the finger biometric sensor, and determine whether the acquired spoof detection data is representative of a live finger. The processor may also switch from the user-interface locked mode to the user-interface unlocked mode when the acquired spoof detection data is representative of a live finger, and cooperate with the finger biometric sensor to acquire biometric matching data. The processor may further perform finger matching based upon the acquired biometric matching data and stored biometric enrollment data.

Abstract: An electronic device may include a housing and at least one infrared (IR) proximity sensor carried by the housing. The at least one IR proximity sensor may include an IR emitter configured to emit IR illumination toward a user, and an IR sensor configured to sense reflected IR illumination from the user. The electronic device may also include a camera carried by the housing and configured to capture an image of the user's face based upon the reflected IR illumination. The electronic device may further include a controller configured to apply facial recognition to the captured image of the user's face based upon the reflected IR illumination.

Abstract: In a conventional Time Division Multiple Access (TDMA) wireless system, the specified distance between a mobile unit and the base transceiver system (BTS) cannot exceed predetermined distances because of time slot synchronization constraints. Furthermore, the varying distances between mobile units and the BTS create timing differences in the random access control channel (RACCH) bursts in the initial uplink signal from the mobile stations. In this approach to extending TDMA system coverage, in-band translator components are located in the center of remote cells which would normally contain a base transceiver system. The in-band translators include a loop back circuit that permits a host BTS to measure the backhaul propagation time delay by sending test access signals between the host BTS and the distant in-band translators.

Abstract: A control message communication mechanism for use in a broadband transceiver system that includes multiple digital signal processors for performing real time signal processing tasks. One of the digital signal processor (DSPs) is designated as a master DSP. The remainder of the DSPs are arranged in rows and columns to provide a two-dimensional array. A pair of bit-serial interfaces on each DSP are connected in a vertical bus and horizontal loop arrangement. The vertical bus arrangement provides a primary mechanism for the master DSP to communicate control messages to the array DSPs. The horizontal loop mechanism provides a secondary way for DSPs to communicate control information with one another, without involving the master DSP, such as may be required to handle a particular call, without interrupting the more time critical primary connectivity mechanism.

In this approach to extending TDMA system coverage, in-band translator components are located in the center of remote cells which would normally contain a base transceiver system (BTS). The in-band translators include a loop back circuit that permits a host BTS to measure the propagation time delay by sending test access signals between the host BTS and each in-band translator. The measurements are then used to adjust a time delay in an uplink signal as received from each in-band translator by the BTS in normal operation.
