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.

Handheld medical device functionality without battery

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.

A method and system for dynamic call type detection for circuit and packet-switched networks. A network endpoint, such as a gateway, will receive an incoming signal and make an examination of the signal to detect characteristics of the signal. Upon detection of a characteristic of the signal, the gateway will generate a data packet, identifying the characteristic, and send the packet to a receiving network endpoint. The initial gateway will continue to examine the incoming signal and continue to send packets identifying characteristics of the signal as more characteristics are detected. The receiving gateway may then begin reproducing the signal in part by generating a signal that has the characteristics as indicated by the data packets. Once the initial gateway no longer receives the incoming signal, and determines that an event has occurred, the gateway will send a packet to the receiving gateway to inform it of the event.

Method and system for dynamic call type detection for circuit and packet switched networks

A method and system of setting up a call over a circuit or packet switched network. Network elements exchange an automode sequence of signals to determine a modulation that both devices support and that will be used for the connection between them. The two elements may exchange the automode signals end-to-end, and then switch to a modulation scheme by negotiating an appropriate modulation or one supported by both endpoints. Alternately, each element can execute a split automode sequence with a separate network endpoint to determine the modulation to be used between the network elements. The network elements and network endpoints may negotiate a modulation scheme by exchanging integers that are indicative of the capabilities of the network elements to determine which supported modulation scheme is most desirable in the particular configuration of the elements.

Method of communicating between network devices through gateways using call discrimination options

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.

A method and system for detecting analog and Adaptive Differential Pulse Code Modulation (&ldquo;ADPCM&rdquo;) 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. If the absolute value of the transmitted signal is greater than a threshold value, the offset is detected indicating the presence of a digital end-to-end transmission channel. If the absolute value of the integrator is less than a threshold value, the D.C. offset is not detected indicating the presence of an analog link in the transmission channel.

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.
