    Abstract: An integrated circuit includes an output pad, an alarm output pad, and a test mode output pad. A first multi-bit register is programmable to store programmable data such as data that identifies a customer for whom the integrated circuit has been manufactured. A second multi-bit register is programmable to store customer specified threshold data. A first circuit selectively couples the first and second multi-bit registers to the output pad. The first circuit is operable responsive to the integrated circuit being placed into a test mode to perform parallel-to-serial conversion of either the customer identification data stored in the first multi-bit register or the customer specified threshold data stored in the second multi-bit register and drive the converted data for output through the output pad. The integrated circuit further includes a tamper detection circuit operable responsive to the customer specified threshold data to generate a tamper alarm signal. A second circuit selectively couples the tamper alarm signal to the alarm output pad and test mode output pad depending on whether the integrated circuit is in a test mode. More specifically, the second circuit operates to drive the alarm output pad with the tamper alarm signal when the integrated circuit is not in test mode and drive the test mode output pad with the tamper alarm signal when the integrated circuit is in test mode (with the alarm output pad driven to a known state).

    Abstract: An embodiment of a motor controller includes a motor driver and a signal conditioner. The motor driver is operable to generate a motor-coil drive signal having a first component at a first frequency, and the signal conditioner is coupled to the motor driver and is operable to alter the first component. For example, if the first component of the motor-coil drive signal causes the motor to audibly vibrate (e.g., “whine”), then the signal conditioner may alter the amplitude or phase of the first component to reduce the vibration noise to below a threshold level.

    Abstract: A protocol for resolving shared spectrum contentions in cognitive radio wireless access networks is presented. Using medium access control level messaging a request for access to a shared spectrum is conveyed to the current occupier of the spectrum. Each request is associated with a unique and random spectrum access priority number. At the end of a request window the priority numbers associated with each request are compared and a winner is declared. The winning cell, informed of its newly gained access to the shared spectrum, sends a reply to the current occupier of the shared spectrum with a proposed time of acquisition/release of the shared spectrum. The proposed time is confirmed and announced, and upon arrival of the designated time the shared spectrum is released by the current occupier of the shared spectrum and acquired by the requesting cell.

    Abstract: For enhanced interoperability of safety and non-safety communications, a synchronous interval is divided into a safety channel interval and an open interval instead of a CCH (control channel) interval and SCH (service channel) interval. For a single-radio device, a control interval, in place of an open interval should be scheduled at least once every maximum service scheduling period. Such a control interval is dedicated for CCH (and SCH) operation. For a multi-radio device, a control interval is scheduled at least once every maximum control interval on one of the radios support non-safety services (e.g. tolling).

    Abstract: Described herein are various principles for designing, manufacturing, and operating integrated circuits having functional components and one or more metal interconnect layers, where the dimensions of signal lines of the metal interconnect layers are larger than dimensions of the functional components. In some embodiments, a signal line may have a width greater than a width of a terminal of a functional component to which the signal line is connected. In some embodiments, two functional components formed in a same functional layer of the integrated circuit may be connected to metal signal lines in different metal interconnect layers. Further, the metal signal lines of the different metal interconnect layers may overlap some distance.
