Abstract: In one aspect, a phone-interface device determines whether a problem has occurred at a control panel by determining whether a signal from the control panel has been received, and when a signal has not been received within a period of time, the phone-interface device transmits an error message to a monitoring station. In another aspect, the control panel determines whether a problem has occurred at the phone-interface device by determining whether a signal from the phone-interface device has been received, and when a signal has not been received within a period of time, the control panel transmits an error message to a user. In another aspect, the phone-interface device contains memory to buffer data transferred between the control panel and a monitoring station. In this way, a high-speed connection between the phone-interface and the monitoring station can be accommodated while using a lower-speed connection between the phone-interface device and the control panel.

Abstract: The invention relates to a system and a method for the detection of the wear state of machine parts which are subject to mechanical wear, by means of an electronic transmitting/receiving device (38) and at least one transponder device (36), which is embedded in the machine part (16) and sends back an acknowledgement signal in response to a transmitted signal which is transmitted by the transmitting/receiving device (38), in which case the reaching of a predetermined wear value can be indicated by the destruction of the transponder device (36) and by the lack of the acknowledgement signal associated with this. The invention is based on the discovery that the arrangement of a transponder device at a specific position which is a measure of a predetermined wear state means that the operational readiness of the transponder device, on the one hand, is indicated in advance by its signal return, and the reaching of the predetermined wear value is indicated by its destruction.

Abstract: An implantable medical device includes a dual-use sensor such as a single accelerometer that senses an acceleration signal. A sensor processing circuit processes the acceleration signal to produce an activity level signal and a heart sound signal. The implantable medical device provides for rate responsive pacing in which at least one pacing parameter, such as the pacing interval, is dynamically adjusted based on the physical activity level. The implantable medical device also uses the heart sounds for pacing control purposes or transmits a heart sound signal to an external system for pacing control and/or diagnostic purposes.

Abstract: The present invention is directed toward a communications channel comprising a link level protocol, a driver, a receiver, and a canceller/equalizer. The link level protocol provides logic for DC-free signal encoding and recovery as well as supporting many features including CRC error detection and message resend to accommodate infrequent bit errors across the medium. The canceller/equalizer provides equalization for destabilized data signals and also provides simultaneous bi-directional data transfer. The receiver provides bit deskewing by removing synchronization error, or skewing, between data signals. The driver provides impedance controlling by monitoring the characteristics of the communications medium, like voltage or temperature, and providing a matching output impedance in the signal driver so that fewer distortions occur while the data travels across the communications medium.

Abstract: A hearing aid includes a microphone for providing an electrical signal representative of a received acoustic signal, a means for filtering the electrical signal and a means for automatic switching. Upon detecting a presence of a magnetic field, the means for automatic switching enables the means for filtering to modify a frequency response of the hearing aid to boost a low frequency gain and reduce a high frequency gain. Such filtering can be used with or without a telecoil. A hearing aid including a telecoil is configured with a preamplifier, a inductive element, and a switch control integrated onto a single common circuit board.

Abstract: A wireless coordinate input system for a display system includes a stylus that transmits ultrasonic energy to a plurality of ultrasonic receiving stations in a projection plane. In an embodiment, the stylus may include one ultrasonic transmitter used for determination of three-dimensional coordinates of the stylus relative to the projection plane. The stylus may also include a second ultrasonic transmitter controlled by a pressure-activated switch. When the stylus is pressed against the projection plane, the second transmitter turns on and is used for determination of two-dimensional coordinates of the stylus in the projection plane. The stylus may also include a higher frequency burst transmitter used to generate a time reference. One or more of the ultrasonic receiving stations may also include an ultrasonic transmitter for calibration.

Abstract: Hardware-enforced zoning is provided in Fibre Channel switches to protect against breaching of assigned zones in a switch network which can occur with software-based zoning techniques. The invention provides logic for performing a hardware-based validation of the Source ID S_ID of frames both at the point where the frame enters the Fibre Channel fabric, and at the point where the frame leaves the fabric. The S_ID is verified against an inclusion list or table of allowable S_IDs, which can be unique for each fabric port. The invention provides a way to increase the range of sources an inclusion table can express, by implementing wild cards, on an entry-by entry basis. If the S_ID is valid, it will enter the fabric and route normally. If invalid, the frame will not be routed but will be disposed of by the fabric according to FC rules.

Abstract: This invention generally relates to discontinuous conduction mode switch mode power supply (SMPS) controllers employing primary side sensing. We describe an SMPS controller which integrates a feedback signal from a point determined by a target operating voltage to a peak or trough of an oscillatory or resonant portion of the feedback signal when substantially no energy is being transferred to the SMPS output. When regulation is achieved this value should be zero; the difference from zero can be used to regulate the output voltage of the SMPS.

The module register monitors a system command bus for read and write commands. In response to detecting a read or write command, the module register generates an active termination control signal to the memory. The memory turns on active termination based on information programmed into one or more mode registers of the memory. The memory maintains the active termination in an on state for a predetermined time based on information programmed into one or more mode registers of the memory.

Abstract: A semiconductor device package includes multiple built-up layers of metal sandwiching non-conductive layers. The metal layers have grids of degassing holes arranged in rows and columns. The rows and columns are locatable via a first coordinate system. Signal traces are embedded within the non-conductive layers such that the signal traces are also sandwiched between the metal layers with degassing holes. The signal traces generally run at zero degrees, 45 degrees, and 90 degrees relative to a second coordinate system. The first coordinate system is rotated relative to the second coordinate system to lower impedance variations of different traces. Impedance variations decrease due to the decreased variation in the number of degassing holes passed over or under by a trace. The grid of degassing holes on one metal layer can be offset in two dimensions relative to the degassing holes on another layer.

An article that exhibits a stress-relief layer and a stress-compensation collar is also included. A computing system that includes a stress-relief layer and a stress-compensation collar is also included.

Abstract: In a method for controlling the use of a program signal in a broadcast system, comprising one or more broadcasters and a number of receivers, at least a part of the receivers can be provided with a storage medium for storing program signals. The program signal comprises content signals of a first and a second type, wherein the second type of content signals is inserted in time slots in the first type of content signals. At least the first type of content signals is scrambled using control words as scrambling keys to obtain a scrambled program signal. The program signal is scrambled using control words as scrambling keys and the scrambled program signal is broadcasted together with entitlement control messages (ECM's) containing the control words in an encrypted manner using a second key. Decrypting means are provided at each receiver for retrieving the control words from the ECM's by decrypting the ECM's, wherein the control words are delivered by the decrypting means for descrambling the program signal.
