Patent CA-2343998-A1 (CA)
Title: Guide grip
Inventor: KEHLING RICHARD E
IPC: B62H7/00
Filed: 2001-04-20
Abstract: Learning how to ride a bicycle is not an easy stint for a child. This invention is specifically designed for a 16" bicycle.   Learning how to ride a bicycle can become very devastating for the child. Slow progress for example can easily lead to frustration, the child may become disheartened and perhaps enough dismay to abandon the learning opportunity. Physical injury and possibly even death could result from the collisions with the ground, stationary objects and oncoming traffic that might occur in learning to ride a bicycle.   To make learning of how to ride a bicycle for a child more effortless and gain balance and self confidence during the training, the inventors designed a "Guide Grip".   In order to carry out the task of balancing the bicycle for the child, the trainer has to walk beside the bicycle and child while in motion. In the past the trainer had to walk beside the bicycle and child in a stooped position and without any designated point on the bicycle to get a firm grip on the bicycle for guidance. This posture of course is very awkward and literally backbreaking situation.   Likewise, there can be discontentment and disillusionment by the trainer about achievement and progress of the child in learning how to ride a bicycle.   To make it possible for the trainer to walk in an upright position beside the bicycle inventors created a type of handle, called "Guide Grip". It enables the trainer to provide the optimum balance required for the rider to learn to safely ride a bicycle.

Inventor: SCHIFF LEONARD N
IPC: H04J13/00
Filed: 1999-09-29
Abstract: A method and apparatus for transmitting common information to a plurality of user terminals within a geographic region. The method and apparatus are useful in a satellite communication system (100) having a gateway (120, 122), and a plurality of satellites (116, 118) that orbit such that they are not stationary with respect to a point on the surface of the Earth. The method includes the step of generating a list identifying a plurality of common data channels (702) over which the common information will be transmitted. The list can include, for each of said plurality of common data channels, information identifying a predetermined satellite, beam (401-416), frequency, and channel.  Due to the orbiting of the satellites (116, 118), the list changes over time.  The method also includes the steps of transmitting (708), from the gateway to the geographic region (502, 504, 520, 522), the common information on the plurality of common data channels. The method also includes receiving (720), at a user terminal (124, 126), the common information over at least one of the plurality of common data channels.

Title: Resonant switched power converter
Inventor: NAVAS SABATER JOSE ANDRES
IPC: H02M3/28
Filed: 2001-06-07
Abstract: Resonant switched power converter in which the end of a resonant period coincides with the start of a conducting period of a first switching element (11-4), undesirable dead times being avoided during the operation of a self-excited synchronous rectifier (11-6). To achieve this, a first capacitor (11-8) is added which has the characteristic that its capacitance is a function of the duty cycle of the first switching element (11-4). The variation in the value of the capacitance of the first capacitor (11-8) is implemented by adding in parallel thereto a serial combination of a second capacitor (11-8-1) and a second switching element (11-8-2). The value of the capacitance varies between a first value and a second value.

Title: Downhole bypass valve
Inventor: MCGARIAN BRUCE
IPC: E21B21/10
Filed: 2000-02-25
Abstract: The present invention relates to bypass valves for use in wellbores, particularly but not exclusively to bypass valves used during the setting of hydraulic anchor packers. A bypass valve (2) is provided with a piston (30) slidably mounted adjacent a body member (4) having at least one opening (20) extending therethrough. The piston (30) is moveable between a first position establishing a passage from the interior of the body (4) to the exterior thereof via the at least one opening (20) and a second position isolating the interior of the body (4) from the exterior thereof. Means are provided for increasing, in response to a predetermined fluid pressure differential across the length of the piston (30), the force exerted on the piston (30) by a given flow of fluid through the bypass valve (2) such that the resultant force on the piston (30) is insufficient to move the piston (30) to the second position. Thus, the bypass valve (2) is adapted to provide an indication at the surface of an imminent closure. Once said indication is received, the bypass valve (2) may be closed, without the need for remedial action, by simply increasing the rate of fluid flow.
