Patent CA-2180151-A1 (CA)
Title: System and method for in vivo calibration of a sensor
Inventor: TRIMBLE BRETT A
IPC: A61B5/00
Filed: 1994-12-29
Abstract: Calibration apparatus and method for calibrating a movable pressure sensor (18) include the use of a stop device (98) to establish a reference position outside the sensing movement range of a first sensor. While in vitro, a reference pressure is established by applying pressure to the sensor (18) to move it against the stop surface (98) with a controllable pressure source (56). This reference pressure is stored (30). During use when the sensor is in an unknown position, such as when in vivo, the controllable pressure source applies pressure to move the sensor against the stop surface and the pressure required to do so is measured (62). The measured pressure is compared to the reference pressure to determine the unknown pressure and the system is then recalibrated. An optical system (42) may be used as a second sensor to determine the position of the first sensor. Inner (96) and outer (92) housings in which the first sensor and stop surface are mounted are moved in relation to each other and the optical sensor during assembly of the calibration system to accurately and independently calibrate the first and optical sensors.

Title: Cycle, tensioned spoked wheel assembly and hub therefor
Inventor: DIETRICH ROLF
IPC: B60B1/00
Filed: 1996-10-11
Abstract: Improvements in rear bicycle wheels are disclosed. The improvements afford more balanced torque transmission as between the proximal spokes, adjacent to the multiple sprockets and the distal spokes which are opposite from the sprockets. In one embodiment, torque balancing is achieved by providing the hub with a distal hub flange which has a diameter which is substantially larger than the proximal hub flange. Excellent results have been achieved in a wheel with a hub having a proximal hub flange with a diameter of X and a distal hub flange with a diameter of approximately 1.5 X. According to another embodiment, a wheel according to the present invention is provided with radially oriented proximal spokes and tangentially oriented distal spokes. This shifts the majority of the torque transmission tasks to the distal spokes which, as noted above, are under less tension than proximal spokes under static conditions. In yet another embodiment, a wheel according to the invention includes a novel hub in which torque is transmitted to the hub at a point between the distal and proximal hub flanges, but closer to the distal hub flanges.

Title: Combinatorial libraries having a predetermined frequency of each species of test compound
Inventor: LEBL MICHAL
IPC: G01N33/543
Filed: 1995-12-07
Abstract: A technique is disclosed for generating nonrandom combinatorial libraries on solid phase supports in which each of a set of predetermined species of test compounds is present on a predetermined number of solid phase supports, preferably on only one, and each solid phase support has only a single species of test compound. Each of the predetermined species of test compounds is prepared with absolute certainty because the technique does not employ any random division of the solid phase supports. Rather, the method is based on the stepwise division of a continuous solid phase support matrix prior to each synthetic step in which more than one type of subunit is added. Non-limiting examples of matrices of the solid phase supports include polypropylene membranes, polytetrafluoropropylene membranes and cotton thread. The combinatorial libraries made by the technique are also disclosed.

Title: Measuring device for a hay baler
Inventor: MCPHERSON BOBBY ROY
IPC: A01F15/14
Filed: 1997-10-03
Abstract: Hay bale measuring apparatus utilizes two measuring wheels for measuring the string used by the baler, and indicating the amount of string to a control and display unit. The baler operator sets the desired hay bale size and monitors the baler operation on the display. The control and display unit generates a signal which indicates to the baler when it is time to tie off a bale of hay. The measuring wheel includes a plurality of teeth and is used with an optical beam generator and optical beam detector. String is wrapped once around the wheel and turns the wheel as it is pulled by the baler. As the wheel turns, the teeth interrupt the beam from the beam generator, forming a series of bursts of light. The beam detector generates a burst of current coincident with each burst of light, and sends it to the control and display unit. The conventional bale measuring assembly is completely removed and replaced by a mechanical arm, controlled by the control and display module and capable of moving down or pivoting out of the way of the gear dog used to trigger the tying mechanism.

Title: Multi-frequency remote communications system
Inventor: JANKE JAMES
IPC: G01M3/24
Filed: 1997-11-07
Abstract: This  invention  relates  to  remote  two-way  data communication between units through the wall of a pipeline, storage tank or other containment vessel.  The efficient control of devices deployed within metal containment vessels such as pipelines or storage tanks is difficult without intrusion into the vessel by wires.  Prior art systems have been limited in range and speed of  data  transfer.   The present  invention comprises a control unit located remote from the containment vessel and capable of two-way RF communication with a translator unit located on the outside of the containment vessel.   The translator unit is capable of two-way RF communication with the control unit and two-way EM communication at low frequency with a  command  unit  attached  to  a  device  located  inside  the containment vessel.  Signals sent from the control unit to the translator  unit  are  converted  to  low  frequency  EM  and transmitted through the wall of the containment vessel to the command unit for controlling the device inside the vessel. Signals and data from the device inside the vessel are sent by low frequency EM back through the vessel wall to the translator where they are converted to RF for transmission to the hand held control unit located remote from the containment vessel.
