Patent CA-2331305-A1 (CA)
Title: Automatic power adjustment system for introductory use of a vibrating device on a human body
Inventor: MCCOY WILLIAM G
IPC: H02J7/00
Filed: 1999-05-06
Abstract: Driving power for a vibrating device (10) is provided at less than full level when the device is initially used. Power is gradually increased in successive steps after a selected number of uses in each step until full power is achieved. Also, a battery-energized driving signal for a vibrating device has a selected characteristic, such as duty cycle, which is set initially at less than an optimum value, when the battery which is contained within the driver assembly (22) is at full strengh. As the battery discharges, the selected characteristic is adjusted toward optimum so as to compensate for reduction in the battery voltage and ensure full power output.

Patent CA-2335767-A1 (CA)
Inventor: RIMHAGEN THOMAS
IPC: H04L12/28
Filed: 1998-11-27
Abstract: In a mobile communications system that provides packet data services, a packet data connection is established between a mobile station and a radio access network. The state of the connection is used to specify one of plural different types of radio channels bearing the connection over the radio interface. The connection state preferably also may specify other parameters including, for example, one of plural different mobility management schemes tailored to the selected channel type or channel bit rate(s). The connection is dynamically adapted to an optimal state based on one or more conditions relating to the connection. For example, one or more traffic parameters are determined for the connection and may be used to predict a future value of that parameter. Based on the predicted parameter value or values, an optimal connection state is determined and implemented. If the predicted parameter value changes later in the connection, another connection state may be dynamically selected that is better suited in accordance with the newly predicted parameter value. One example embodiment is based on the amount of data in queue for a packet data connection. Comparison is made with one or more thresholds to decide which type of radio channel should bear the connection. Other factors, parameters, and conditions may be employed along with threshold comparisons to select the optimal radio channel type.

Title: Liquid-phase adsorption process for removing and concentrating heteroatom compounds in hydrocarbons
Inventor: MIN WHA-SIK
IPC: B01J20/10
Filed: 2000-01-18
Abstract: Disclosed is a liquid phase adsorption process for removing and concentrating heteroatom compounds in hydrocarbons (HCH), comprising the steps of adsorption, copurging and regeneration. In the adsorption step, a liquid hydrocarbon stream is fed to an adsorber, which adsorbs HCH and returns adsorption effluent. In the copurging step, HCH, which are extracted from the previous regeneration, are applied to the adsorber, displacing copurging effluent. In the regeneration step, a polar solvent is flowed through the adsorber, purging HCH. Most of the HCH are then set aside for being used in the next copurging step while a small amount of the HCH are taken out from the process as HCH product. The present invention is economically advantageous in effectively removing HCH from the hydrocarbon stream and increasing HCH concentrations within HCH product.

Abstract: An optical device (100) includes a diode light source (200) which is preferably in the form of an array of diode elements (210) such as laser diodes or light emitting diodes (LEDs). The light (150) emitted from the diode elements (210) is directed towards a reflector (240) which directs the emitted light (150) through a heat sink member (270) for controlling the temperature of the diode elements (210). The heat sink member (270) preferably has a plurality of fins (274) for dissipating heat, and the emitted light (150) passes through these fins (274) and away from the optical device (100). An optical lightguide (140) may be integrated with the optical device (100) to give the user better control over how the emitted light (150) is imaged. The diode elements (210) preferably emit in either the blue or ultraviolet region of the optical spectrum.
