Title: Tonneau cover tension adjuster apparatus
Inventor: SCHMEICHEL CHARLES MILTON
IPC: B60J7/10
Filed: 1999-03-19
Abstract: A tonneau cover is provided that is attached at its most forward end to an adjustable tensioning rail which spans the front end of a pickup truck box. The tensioning rail is adjustably attached at its outside edges to two side rails which are attached to the inside of a pickup box. The adjustable attachment of the tensioning rail to the side rails is accomplished by the use a tensioning screw and two attachment blocks. As the tensioning screw is moved forwards and backwards by the use of the adjustment knob, the tensioning rail is moved in a corresponding manner.      This adjustment is preformed when the tonneau cover is in the open position, and thus, allows a user to obtain the desired amount if tightness when the tonneau cover is subsequently placed in the closed position.

Title: Method and equipment for transmitting terminal interface user data and status information
Inventor: RAESAENEN JUHA
IPC: H04Q7/22
Filed: 1997-10-17
Abstract: The invention relates to a mobile system in which the radio interface rate of a traffic channel and the intermediate rate of a transmission channel restrict the number of bits available for the transmission of terminal interface statuses (S), network independent clocking (N) and subchannel numbering (#) of a multichannel data link.

Patent CA-2282819-A1 (CA)
Title: Running board lighting assembly
Inventor: HOFFKNECHT MARC OLIVER
IPC: F21K9/60
Filed: 1999-09-21
Abstract: A running board lighting assembly consisting of an array of LEDs, a lens tube and a power circuit provides distributed light to the surface of a running board step which appears to be evenly distributed and which, when reflected from the running board step surface, appears to have a near incandescent quality. The LED array includes conventional green LEDs, which also emit longer wavelengths, horizontally and evenly spaced within the lens tube. The lens tube is installed within the running board cladding, above the running board step. The lens tube is extruded from acrylic material containing appropriate dye, so that when light from the green LED array passes through the lens tube, the green wavelengths are blocked and the yellow and some red wavelengths are passed, causing the resulting light reflected off the running board step to have a near incandescent appearance. The LEDs are interleaved in strings of four each, so if one string fails, the failure will be nearly imperceptible. The power circuit connects to the vehicle battery and regulates the current passing through the LED array. The power circuit also controls the on/off state of the running board lighting assembly according to the state of the courtesy lights and the on/off state of the vehicle's engine.

Title: E-mail communication apparatus, image communication apparatus having the same, internet facsimile apparatus, and e-mail communication method
Inventor: AKIMOTO MASAO
IPC: H04N1/00
Filed: 1999-09-09
Abstract: An input value from a panel is analyzed by mail address analyze means. A determination section performs determination based on the analysis result. When an identification character "@" is detected in the input value, the determination section instructs an encryption processing section to execute encryption processing, which is made to correspond to the identification character "@". A mail transmitting section transmits data subjected to encryption processing in accordance with an e-mail transfer protocol. An operator has only to add the identification character "@" to a recipient address from the panel so that an image communication apparatus executes encryption processing. This eliminates the need for adding a new button when a new function is added to the image communication apparatus.

Patent CA-2285356-A1 (CA)
Inventor: DANIELIAN ARMEN
IPC: A63H11/06
Filed: 1999-01-28
Abstract: A toy producing a jumping or bouncing action includes an outer body depicting a fanciful animal and an interior support structure which includes an elongated body housing having a head portion and supporting a tail portion. A pair of leg units having a corresponding pair of supporting feet are slidable within the body housing and are joined by a transversely extending leg unit bridge. A gear drive unit includes an electric motor and a plurality of drive gears which rotate a gear segment. The gear segment engages a gear rack on the leg unit bridge and is operative when the motor is energized to drive the toy figure toward a squatting position as the leg units are drawn into the body housing. A spring is coupled between the leg unit bridge and the body housing and is stretched as the gear segment rotates lifting the gear rack. When the teeth of the gear segment move out of engagement with the gear rack, the spring produces a thrusting force upon the leg units causing the toy to bounce or jump. The action repeats until a timer within a control unit operative upon the motor has timed out a predetermined interval.
