Title: Illumination of displays
Inventor: BEESLEY GRAHAM E
IPC: G09G3/34
Filed: 1992-11-27
Abstract: ABSTRACT         A problem arises in electronic equipment incorporating a display, such as an LCD display, which is not intrinsically illuminated.   The present invention provides a controlled backlight for such displays, and is particularly useful in battery-powered equipment where power consumption must be kept to a minimum.    The circuitry comprises a display 1 controlled via a conventional display driver 6 from other equipment (not shown) such as a microprocessor. Whenever the display is changed a signal is sent also to a timer circuit 7 which triggers, and passes a control signal to an electronic switch 4 which in turn passes power from a battery 3 to a lamp 2.   The lamp 2 is arranged to illuminate the display 1.   After a preset period, the timer circuit 7 sends a further control signal to the switch 4 to switch lamp 2 off.     Figure 1.

Patent CA-2123863-A1 (CA)
Inventor: BIANCHI RALPH A
IPC: E02B15/10
Filed: 1994-05-18
Abstract: An oil skimmer (10) employs a dynamic-inclined-plane module (22) that is retractable so that it can be kept suspended above the water during skimmer travel to and from oil-spill sites. The thrust required of the skimmer's propulsion system to achieve a given transit speed is thus much lower than that required by conventional dynamic-inclined-plane systems. When the skimmer (10) reaches the oil-recovery site, the retracting mechanism (26) lowers the dynamic-inclined plane module to its operating depth. To enable the skimmer to operate close to shore, its primary buoyancy is provided by inflatable pontoons (12), which result in shallow draft and relatively low vulnerability to hull damage.

Title: Frequency synchronized bidirectional radio system
Inventor: DAVIDOV MIRCHO A
IPC: H04L25/06
Filed: 1993-01-08
Abstract: A bidirectional radio system for low cost, high through-put accumulation of data from a large number of site units. The site units are connected to remote radio transceivers in radio communication with a plurality of base stations (44). Accurate frequency synchronization allows multiple carriers within a 12.5 kHz FCC bandwidth.  Frequency synchronization is achieved at !ow cost by transmitting a high accuracy carrier and clock signal at a base station, and using receiving circuitry (54) at remote stations to ex-tract the base clock signal and base carrier frequency and a phase-lock loop (258 and 248) to stabilize the remote station carriers. The reception circuitry at a remote station provides independent carrier frequency and clock rate recovery, a phase-lock loop at baseband, and a coarse clock rate recovery circuit (316) coupled to a fine clock rate recovery circuit (320). Remote station re-sponses are time domain multiplexed. A base station receiver can decode a very short remote station response by scaling the re-sponse with the phase and amplitude of an initial segment of the response.  Spatial reuse of carrier frequencies further increases the rate of data throughout.

Title: Multi-master supervisory system
Inventor: PARKHIDEH MEHRALI
IPC: H04L12/24
Filed: 1994-06-23
Abstract: A supervisory system for a network of communications stations in which a response to a query to one station may be received and interpreted by a plurality of other stations in the network. Upon receipt of a command from a master station, a slave station sends a responsive signal that includes the identity of the command. Each master station monitors the network and keeps track of the status of each slave station by updating its status records upon receipt of one of the responsive signals containing the command identity. Each master station operates independently and all of the stations may be master stations. The multiple master stations may each attempt to exert control over the slave stations in the network.

Patent CA-2130814-A1 (CA)
Title: Skate Brake
Inventor: WALIN RICHARD D
IPC: A63C17/14
Filed: 1993-02-25
Abstract: A skate and skate brake which allows a user to brake the skate smoothly and evenly without catching on a ground surface utilizes a rotatable assembly having a resilient outer circumferential member attached to a relatively hard inner hub, the rotatable assembly brakes the skate by rotating with a rotational friction greater than that of the average rotational friction of the skate wheels. The rotational friction of the rotatable assembly is controlled by locating a non-rotating brake pad in physical contact with the inner hub. The amount of rotational friction can be increase by urging the brake pads against an annular portion of the inner hub and by positioning the brake pads within an interior recess inside the inner hub so that an increase in the downward force that the user applies to the brake increases the force by which the inner hub of the rotatable assembly is urged against the brake pads. A method for braking a skate includes the steps of pivoting the skate about a wheel, rotating a rotatable assembly in contact with a ground surface while applying friction to the rotation of the rotatable assembly by urging a non-rotating brake pad against a relatively hard interior surface of the rotating rotatable assembly.
