Filed: 1998-07-20
Abstract: A high clearance vehicle includes a walking beam frame and an independent suspension. The frame consists of a main frame, A-shaped frames, a main truss, leg braces, and an axle. Pins which are used to join each A-shaped frame and leg braces to the main truss act as pivot points, as does the pin that attaches the axle to the main frame. Each leg brace may connect to each A-shaped frame by an elastic member to provide the independent suspension. Legs are at each corner of the frame. At the bottom of each leg is a wheel hub mount with a wheel drive assembly operably connected to a wheel for propelling the vehicle. At the top of the front legs are tapered kingpins which carry segmented thrust washers having a knob and receiving portion. A boom having extension arms and spray nozzles may also be attached. The walking beam frame may include a crab steering device which shifts the rear axle off-center so that the vehicle dog legs. A hinge stacked assembly includes a self cleaning screen, a condenser, oil cooler, and a radiator. Angled hinges allow a door to be opened away from the vehicle and the rear tire so that the stacked assembly is easily accessible to maintenance. A knee action suspension may also provide independent suspension to the vehicle. The boom may have upper and lower lift arms. An elastic member may be provided for supporting the lower lift arm.

Inventor: KARLSSON SVEN
IPC: B41J2/175
Filed: 1997-05-05
Abstract: Système auxiliaire d'alimentation en encre pour imprimantes, tables traçantes, copieurs et télécopieurs à jet d'encre comprenant un réservoir (10) d'alimentation auxiliaire externe, une ligne (30) d'alimentation pourvue d'une gaine (35) spiralée pour empêcher le tortillement de la ligne et un dispositif d'apport d'encre dans la cartouche (2) par le clapet de non-retour à dépression (de formation de bulles) situé dans le fond de la cartouche (2). L'installation d'alimentation du clapet de non-retour consiste de préférence en une poche aplatie comprenant une bande double face pour la fixer sur le fond et sur l'arrière de la cartouche (2). On peut utiliser à la place de ce système une plaque de base collée par adhésif. L'alimentation (10) en encre auxiliaire externe est de préférence une poche (11) placée dans une boîte. Le système fonctionne sous l'effet du vide et non de la gravité, le vide créé dans la cartouche (2) attirant l'encre depuis le réservoir auxiliaire jusqu'à l'intérieur de la cartouche (2) en passant par la ligne (30) d'alimentation. Cette dernière (30) n'a pas besoin d'être amorcée ceci évitant les fuites lors de la mise en place. Etant donné que le remplissage s'effectue par le clapet de non-retour dans le fond de la cartouche et que le niveau d'encre dans le réservoir (10) peut se trouver à une hauteur négative maximale de moins quatre pouces, le système empêche le rétrosiphonnement à partir de la cartouche (2) et le débordement du réservoir externe (10). On décrit des systèmes équipés de plusieurs réservoirs destinés à des imprimantes à plusieurs couleurs. Une fois que l'ensemble d'apport (poche aplatie ou plaque de base) est fixé sur le fond de la cartouche MEO (2), le remplacement ultérieur du réservoir s'effectue au moyen d'un dispositif (31) de connexion torsadé adjacent au réservoir (10). Le système fonctionnant sous pression négative, il n'y a pas de fuite.

Patent CA-2263221-A1 (CA)
Inventor: KONDOU SATORU
IPC: G09G3/20
Filed: 1996-11-20
Abstract: A PLL circuit is provided with a lock/unlock detecting circuit which detects the locked or unlocked state of the PLL circuit by comparing the phases of a horizontal synchronizing signal and a comparing signal with each other and an internal synchronizing signal generating circuit which outputs the comparing signal as an internal synchronizing signal when the locked state is detected or outputs the horizontal synchronizing signal as the internal synchronizing signal when the unlocked state is detected. Another mode of a PLL circuit is provided with a skew detecting circuit which resets a frequency dividing circuit upon detecting a skew which is deviated from a normal period in an external synchronizing signal, generates a dummy pulse upon detecting that no skew occurs in the external synchronizing signal in the normal period, and generates a reference signal in combination of the dummy pulse with the external synchronizing signal. When the skew detecting circuit detects a skew, the circuit also resets a phase comparator circuit. A digital display device having such a PLL circuit prevents distortion of the picture when the PLL  circuit is in an unlocked state or a skew occurs.

Title: A linear surface memory to spatial tiling algorithm/mechanism
Inventor: RADECKI MATTHEW
IPC: G11C7/10
Filed: 1999-03-31
Abstract: A computer graphics system and a method of configuring data in a memory unit of a computer graphics system. Generally, the data is configured such that the number of memory page breaks is reduced when data is accessed from the memory for image computation. For example, when the memory is used to store pixel values, each page of the memory is comprised of pixel values for a rectangular or tile array of pixels. This increases the spatial coherence between the pixel values and the pixels of the polygons that are rasterized when the system renders an image. Preferably, a translation algorithm is provided to allow standard operating systems and software applications to work with the tiled configuration of the pixel values in the memory. This algorithm translates the scalar memory address initially provided by the operating system or the software application, and translates that first scalar memory address to a second scalar memory address that will properly access the value for the pixel conventionally associated with the first scalar memory address.

Title: Onboard control of demand assigned multiple access protocol for satellite atm networks
Inventor: PRIETO JAIME L JR
IPC: H04L12/56
Filed: 1999-12-29
Abstract: An onboard DAMA protocol for use in connection with a processing satellite communications network, where multiple users are assigned to a common transmission resource as part of a sharing set. A media access controller (30) on the satellite maintains a reservation log which identifies the frequencies and number of uplink time slots in the resource that are currently reserved by one or more members of the sharing set. To reserve a time-frequency slot on the transmission resource for a non-contentious transmission of data, a user of the sharing set will transmit a reservation request to the satellite on a contentious uplink resource. If a return message is not received, the user knows that the reservation request collided with another reservation request, and a retransmission strategy of the reservation request is employed. When the media access controller (30) receives the reservation request, it decides whether to grant, deny or delay the request based on the service and price class of the user, the amount of data already sent by the user, the number and type of other users with reservation requests in the queue, and the congestion state of the destination downlink port and subsequent nodes in the network. When the user receives a reservation grant message from the media access controller (30) on the satellite in the downlink, it will then wait for its reservation time frequency slot, and transmit its data in a non-contentious basis on the transmission resource at that time. If the user needs additional bandwidth to transmit more data, it may piggyback a reservation request on the data transfer.
