Patent CA-2282510-A1 (CA)
Inventor: WARD PAUL A
IPC: G01C19/5719
Filed: 1998-02-24
Abstract: A micromechanical tuning fork gyro having two center electrodes (9a, 9b). The two center electrodes are excited with bias potentials of opposite polarity. The oppositely biased center electrodes provide electrical symmetry across the gyroscope and thereby reduce charge transients and sensitivity to vertical translation. Currents injected directly into the proof masses (3a, 3b) are equal and opposite and thus cancel. Motor lift forces acting on the proof masses and interleaved electrodes equal, hence the proof masses move in pure translation, thereby reducing in-phase bias. Further, any pure translation normal to the plane of the gyroscope does not effect sense axis output signals.

Abstract: A method to determine a switching moment (Ti) of a switch (SWi) is provided. The switch is coupled to an optical combiner (OC) of a tree-like optical network. The optical combiner enables multiple access of information signals (IN1, ..., INi, ... INn) which are upstream transmitted from network units (NU1, NU1', NU1", ..., NUi, ..., NUn) to a line terminator (LT) via the cascade connection of dedicated branches (B1, ..., Bi, ..., Bn), the optical combiner and a common branch (BC). The switch passes an information signal (INi) at an approximated switching moment (APP-Ti) when the information signal is present and interrupts the branch when the information signal is not present. The method includes the steps of : a) capturing downstream grant information by a control network unit (CTRL-NU) which is coupled between the switch and the line terminator; and b) determining the approximated switching moment by the control network unit based upon the downstream grant information; and c) upstream transmitting by one of the network units coupled to this one dedicated branch a predefined bit pattern (PAT) similar to the information signal. In the event when the predefined bit pattern is passing through the switch, the predefined bit pattern is truncated and a truncated bit pattern (PAT-TR) is provided which is related to the approximated switching moment; and d) detecting by the line terminator reception of the truncated bit pattern; and e) determining by the line terminator a measure of how much the predefined bit pattern is truncated and providing thereby a truncation measure (.TR); and f) calculating in function of the truncation measure a calibration value (CAL-SWi) for the switching moment; g) providing the calibration value to the control network unit in order to determine the switching moment in function of the calibration value and the approximated switching moment.

Abstract: A tear-away surgical drape is provided by the present invention. The drape has a fluid absorbent pad attached to the upper surface of an underlying base sheet. The drape has an opening, or fenestration, therein through which the operation is to be performed. The absorbent pad has a score line in it which extends from an edge of the pad to the fenestration so that it, like the tear-away material forming the base sheet, may be easily torn away after surgery.  The present drape is particularly useful when it is necessary to leave a tube, catheter, or other apparatus attached to the patient after the surgery. The tear-away aspects of the drape allow it to be removed without disturbing the attached apparatus.

Title: Mobile terminal employing 30khz/200khz carrier identification
Inventor: KANANEN KARI
IPC: H04B7/26
Filed: 2000-03-03
Abstract: A method for use by a multi-mode, dual band mobile terminal (10) for identifying a presence of a GSM1900 carrier that is channelized into first channels having a bandwidth of 200kHz, and for distinguishing the GSM1900 carrier from at least a TDMA1900 carrier that is channelized into second channels having a bandwidth of 30kHz. The method includes steps of (a) tuning a receiver (16) to a frequency of a candidate GSM1900 channel; (b) determining a value of a received signal strength indicator (RSSI) using a 200kHz receiver passband filter; (c) if the RSSI value is above a predetermined threshold, converting the frequency of the candidate GSM1900 channel into a frequency of a TDMA1900 channel using a predetermined relationship; (d) retuning the receiver to the frequency of the TDMA1900 channel; (e) determining a RSSI value using a 30kHz receiver passband filter for the TDMA1900 channel, and also for at least two adjacent TDMA1900 channels, assuming that two adjacent TDMA1900 channels are not used together in a same cell;  and, if the at least three RSSI values are all found to be approximately equal within some threshold value, (f) making at least an initial assumption of the presence of the GSM1900 carrier. A further step can be executed of verifying that the assumed GSM1900 carrier is not actually a CDMA1900 carrier. The method has an initial step of camping on a channel of a carrier in another frequency band (e.g., a TDMA800 channel), and the steps of tuning and retuning are executed without changing a baseband clock frequency from a frequency associated with the channel that the mobile terminal is camped on.

Abstract: A table-top coffee vending machine providing slide-out storage containers for easy filling and removal, a compact fast acting coffee brewing system and a filter paper cutting and storage system. A plurality of storage containers for ground coffee, hot chocolate ingredient and condiment are provided in a rack system that allows the group of containers to be slid out of the machine cabinet on telescoping rails to allow easy filling and removal of the containers. The brewing method includes simultaneously supplying water and coffee grounds to a brewer, stopping the supply of both, allowing the mixture to steep and then beginning to remove the mixture from the brewer while reinitiating the supply of water to the brewer for a sufficient time to supply a complete cup of coffee at a cup station. The filter paper cutter cuts lengths of paper from a continuous supply of filter paper after it is used in the brewer to filter the coffee. The cutter is saw-toothed and a paper clamping mechanism is used to clamp the paper in the area where it is to be cut. The cut lengths of paper are collected in a removable tray and are compressed into a stack by a sweeper bar that is activated in conjunction with the cutter action.

Abstract: An emergency services call is routed from a mobile station to a selected Public Safety Answering Point (PSAP) in a cellular network. The system intelligently selects one of a plurality of PSAPs, warns the selected PSAP, prior to call routing, that the emergency services call is coming, and provides the selected PSAP with advanced information regarding the context of the call. A serving mobile switching center (MSC) sends cell or sector information to a service control point (SCP). The SCP includes a PSAP selector which selects the PSAP based on such information as the mobile station location and current time. The SCP then sends an alerting signal to the selected PSAP and includes a tag and information relating to the context of the call. The SCP then returns the tag and the identity of the selected PSAP to the serving MSC which delivers the call to the selected PSAP.

Title: Flexible multiple compartment medical container with preferentially rupturable seals
Inventor: SMITH STEVEN L
IPC: B31B41/00
Filed: 1998-10-01
Abstract: A flexible container (10) is provided for the storage and mixing together of diluents and medicaments. The container incorporates multiple compartments (18, 20, 22) separated by preferentially peeled seals (24, 26) in which the diluents and medicaments are stored.  The container is constructed of thermoplastic materials having high oxygen and moisture barrier properties which allows the container to be stored for extended periods of time without degrading the contents. The peelable seals are ruptured by manipulation of the container to thereby mix the contents together for delivery through standard IV  arrangement to a patient. The container is fillable with a single component liquid medicament which may be susceptible to sloshing or turbulence. Turbulence is minimized by eliminating the internal gaseous head space by initially forming the head space with a low molecular weight gas such as helium.
