Title: Present/absent mode temperature control
Inventor: EDMONDSON ROBERT E
IPC: G05D23/19
Filed: 1994-02-04
Abstract: The present invention relates to a method comprised of a circuit design for transferring a building's heating or cooling system, either central or zoned, from one temperature level to another (present and absent modes) by the opening or closing of one single pole single throw switch or set of relay contacts. The absent mode temperature is maintained by a pre-set or adjustable mercury thermometer type sensor (Adjustable sensor U.S. Patent #4,376,928; British Patent #2102948; Canadian Patent #498-457).  Indicating lights show whether the invention is operating in the present or absent mode, The invention can be used singly or two or more can be connected together at a distance to maintain even or different absent mode temperatures in different areas of a building. This connection of two or more of the circuits comprising this invention will not affect the ability of the single set of contacts to transfer the temperature level between present and absent modes at all locations and to have that mode registered at all locations by the absent or present mode indicator lights, To facilitate the field installation of this invention, the disclosure describes a method to secure a printed circuit power relay to the inside of a junction box or junction box cover plate.

Patent CA-2119715-A1 (CA)
Inventor: KUZMA ANDREW J
IPC: H04N7/14
Filed: 1994-03-23
Abstract: Video telephone apparatus 10 for transmitting video information over a limited bandwidth communications channel includes a source 110 of video frames which arecompressed to reduce the amount of redundant information, and to reduce the level of detail according to a user-selected control signal. The video frames are presented to a compressor 500 at a rate which is varied in order to maintain a constant rate data signal at the compressor's output. As the level of detail is decreased the frame rate is correspondingly increased, thus providing the user with the ability to trade off between image clarity and smoothness of motion. Such tradeoffs are useful when the bandwidth of the communications channel is severely constrained. The control signal is transmitted to the video telephone apparatus 10 from a far-end video telephone over the same channel.
Patent CA-2120055-A1 (CA)
Inventor: COMBS JAMES L
IPC: G06F9/46
Filed: 1994-03-28
Abstract: A computer system having four states of power management:  a normal operating state, a standby state, a suspend state, and an off state.  The standby state is characterized by devices, such as a video controller and a hard drive, being placed into a low-power mode transparent to the operating system and the applications executing on the computer system.  The suspend state is characterized by executing code being interrupted and the state of the computer system being saved to a file on the hard drive in such a manner that system power may be removed after the state of the computer system is saved to the hard drive.  Later, after system power is restored, the state of the computer system is resumed by reading from the hard drive and loading it in such a manner that the operating system and application programs are not adversely affected.  The normal operating state and the off state correspond to the typical on and off states of more conventional computer systems.   The suspend/resume/standby feature is implemented at a low cost using many standard components.

Title: Genomic mismatch scanning
Inventor: BROWN PATRICK
IPC: C12Q1/68
Filed: 1993-05-04
Abstract: Genetic mapping is provided by either of two related general procedures. In the first procedure, mapping is provided by identifying genetic regions from which DNA fragments derived from two individuals can combine to form extensive hybrids free of base mismatches. DNA is processed by a method that allows perfectly-matched hybrid DNA molecules formed between DNAs from the two individuals, to be separated from imperfectly-paired DNA hybrids or hybrids in which both strands are from the same individual's DNA. The perfectly-matched hybrid DNAs can then be labeled and the labeled DNA  used as probes to identify loci of indentity-by-descent between the two individuals. In the second prodecure, nicks are introduced specifically into DNA hybrids formed between non-identical alleles from a region of heterozygosity in an individual diploid genome. The nicked DNA molecules are then specifically labeled to provide probes for identifying regions of heterozygosity in the genome of an individual.

Title: Method and system for dynamically selecting a communications mode
Inventor: REYNOLDS DAVID C
IPC: G06F15/177
Filed: 1995-04-03
Abstract: In a multi-processor parallel processing computer environment different  communication  modes  are  available  for  performing  an information  distribution  operation  (e.g.,   a  broadcast)  between processors.  The technique comprises automatically selecting an optimal communications mode at operation run-time.   The selection decision utilizes hardware parameters of the system (e.g., communication speed between processors) and run-time parameters (e.g., number of nodes to broadcast a message to).   The communication mode selection decision seeks to optimize factors such as time required to execute or work space requirements of the distribution operation.

Filed: 1995-04-12
Abstract: A mechanical drive for a dual action motor that is used with an oscillating spindle sander is disclosed.  The oscillating spindle sander has a worktable for supporting a workpiece.  A spindle extends upwardly through the worktable and has a sanding surface.  An electrical motor is supported by the worktable and includes a shaft for imparting rotational motion to the spindle.    The mechanical drive is contained within a housing that is supported by the motor and is connected to the motor shaft for imparting reciprocal or axial motion in addition to rotary motion to the spindle.  The mechanical drive includes a speed reducer that is coaxial with the motor shaft.  The speed reducer drives a cam follower that engages a cam in the housing for imparting reciprocal motion to the spindle at a rate much less than the rotational speed imparted to the motor shaft by the motor.  The speed reducer includes a cycloidal gear that engages a complementary ring gear provided in the housing.  The mechanical drive for the dual motion motor is disclosed as being particularly useful in connection with oscillating spindle sanders; however, other applications are also contemplated.
