3Com Corporation - Santa Clara CA

International Classification:

H04L 516

US Classification:

375222, 375228, 379 93, 370252, 455115, 4552261

Abstract:

A method and system for detecting analog and Adaptive Differential Pulse Code Modulation (âADPCMâ) communication links in a communication channel is described. On an illustrative embodiment, the method include the steps of transmitting a signal with a D. C. offset value across the communication channel, receiving the transmitted signal from the communication channel and detecting the D. C. offset value in the received signal. If the D. C. offset value is detected, the communication channel is determined to be a digital end-to-end connection. If the D. C. offset value is not detected in the received signal, the communication channel includes analog or ADPCM connection links and is not suitable for all-digital communications. In illustrative embodiment, the device includes a transmitter capable of transmitting an offset transmit signal, a receiver capable of receiving the transmitted signal and logic capable of detecting an offset signal. The logic may include an integrator to receive the transmitted signal, an absolute value circuit to determine the absolute value of the integrator output, and a comparator to compare the absolute value of the integrator output to a threshold value.

Abstract:

A method and system for detecting frame slips due to loss of synchronization in a digital communication channel is described. In an illustrative embodiment, a synchronization bit pattern is periodically embedded in the digital data stream. In a described embodiment, the sign bits of the octets of every N frame of data is robbed to form a periodic control channel carrying the synchronization bit pattern. The control channel can be monitored at the appropriate intervals to detect the appropriate synchronization bit pattern. Failure to detect the synchronization bit pattern at the appropriate interval indicates a loss of synchronization such as a frame slip.

International Classification:

A61B 5/145

US Classification:

600365

Abstract:

A system for managing power consumption of a handheld diabetes management device and limiting effects of temperature on operations performed by the handheld diabetes management device comprises a blood glucose measuring module, a temperature sensing module, and a power management module. The blood glucose measuring module selectively measures blood glucose in a blood sample and generates a status signal indicating a status of operation of the blood glucose measuring module. The temperature sensing module senses an internal temperature of the handheld diabetes management device and estimates an ambient temperature external to the handheld diabetes management device. The power management module deactivates one or more components of the handheld diabetes management device based on the status of operation of the blood glucose measuring module when the internal temperature of the handheld diabetes management device exceeds a threshold temperature. The power management module deactivates the blood glucose measuring module when the ambient temperature is greater than a first predetermined threshold or less than a second predetermined threshold.

US Classification:

600365, 36167931

Abstract:

A processor module includes memory having instructions for executing functions of a handheld diabetes management device and a processor that selectively executes the instructions. Battery terminals electrically connect the processor module with a re-chargeable battery. A receptacle is configured in accordance with a universal serial bus (USB) standard. A component is included for communicating information from the handheld diabetes management device to a user or another device. A multiplexer module relays power from the receptacle to a bus voltage node. A first switching device is connected between the bus voltage node and a second voltage node. The component receives power from the second voltage node. A second switching device is connected between the bus voltage node and a third voltage node. The processor module is directly connected to the bus voltage node and to the third voltage node.

International Classification:

H04B 700

US Classification:

455 381

Abstract:

A low powered RF receiver for receiving a modulated carrier having a coded transmission so as to remotely control a number of vehicular devices includes an antenna, a preamp stage, mixer, local oscillator, first and second IF bandpass filters, first and second IF amplifiers, a received signal strength indicator/detector circuit, and an adaptive threshold/filter circuitry. The signal strength indicator/detector circuit is interconnected between the first and second IF amplifiers and generates a strength indicator signal which is proportional to the strength of the modulated carrier signal received. The adaptive threshold/filter circuitry is responsive to the strength indicator signal and has a varied threshold reference level for eliminating noise and for converting the strength indicator signal to a logical level. A microcontroller is provided for further signal processing, decoding, and executing the function corresponding to the vehicular device to be controlled.

International Classification:

H04J 312

US Classification:

370523

Abstract:

Detection and compensation for periodic disturbances in sampled data such as the error introduced by robbed bit signaling (RBS) in a digital carrier system. A period of N samples, e. g. , six or twelve frames, at which the periodic disturbance repeats is identified for collecting a subset of the sampled data, i. e. , samples taken from a common frame. In a digital telephone network (DTN), the RBS disturbance repeats at an integer multiple of 6 frames; signaling bits A, B in a superframe (SF), or at a period of 12 frames. In an extended superframe (ESF), the RBS may repeat every 24 frames, using signaling bits A, B, C, D in one of every sixth frame. An embodiment detects the presence of the periodic robbed bit signaling disturbances in sampled data by integrating the least significant bits (lsbs) of the subset samples from a frame to determine whether in-band signaling is being performed in the frame. Thus, the octets of identified frames may be adjusted by plus or minus a half least significant bit magnitude to compensate for the error introduced by T-Carrier signaling and the like.

Abstract:

A method of producing vehicles comprises: in a vehicle production process, manufacturing vehicle components of different types, and assembling the vehicle components to form vehicles; creating a set of vehicle records, each being a record of one of the vehicles entering active service; performing vehicle repairs on a subset of the vehicles after they have entered active service; creating a respective record of each of the vehicle repairs, each of which comprises or indicates a vehicle age or usage value, and records a vehicle component fault identified in the vehicle repair; receiving at a data processing stage the vehicle records and vehicle repair records, wherein a predictive algorithm executed at the data processing stage processes the received records so as to, for each type of vehicle component: 1) identify a respective set of the vehicle repair records relating to that type of vehicle component, and 2) use the respective set of vehicle repair records to predict a respective number of or resource value for vehicle component faults of that type for the set of vehicle records based on: a number of vehicles recorded in the set of vehicle records, and a current age or usage of each of the recorded vehicles; comparing the predictions for the different vehicle component types to identify a problem with a particular one of the vehicle component types; and adapting the vehicle production process, so as to remedy the identified problem with the particular vehicle component type for later vehicles produced in the adapted vehicle production process.
