Title: Method and apparatus for detecting fault conditions in a vehicle data recording device
Inventor: DOYLE THOMAS F
IPC: G07C5/08
Filed: 1995-10-03
Abstract: A system and method for detecting fault conditions in a recording device (38) disposed within a vehicle (12) having one or more vehicle sensors (48) for monitoring one or more operational parameters of the vehicle (12). The recording device (38) is used to collect vehicle operation data produced by the sensors (48). One implementation of the fault detection technique involves the storing of a current time value at regular intervals during periods in which the recording device is provided with a source of main power. Time differences are determined between consecutive ones of the stored time values, and the time differences compared to a predetermined maximum value. A power loss fault condition is registered when at least one of the time differences exceeds the predetermined maximum value. An indication of the existence of the power loss fault condition may be communicated to a central control station (18) by the recording device (38).

Title: An ink jet recording head, an ink jet head cartridge, and an ink jet recording apparatus
Inventor: HIROSAWA TOSHIAKI
IPC: B44C1/17
Filed: 1997-07-30
Abstract: An ink jet recording head capable of separating or coupling ink tanks from or with the head comprises a recording device substrate having a plurality of recording devices thereon for discharging ink, a wiring device for giving electrical recording signals to the recording device substrate, an ink supply member for supplying ink to the recording device substrate, and a filter member for removing dust particles or the like in ink. This recording unit is provided with all the functions of discharging ink, and coupled with a holder member having only the function of holding and fixing ink tanks. With the structure thus arranged, it becomes unnecessary to connect ink supply paths as in the conventional art, hence eliminating the provision of sealing members. The number of parts is made smaller, while making it possible to carry out inspection of heads only in accordance with the recording units, which significantly contributes to simplifying manufacture and providing highly reliable heads at lower costs.

The tube-carrying sub-assembly is formed by two metal sheets intimately joined to one another, one of which is a flat sheet while the other is provided with a large number of embossings which form the sub-assembly of tubes for the passage of water, which tubes are linked with one another, thus forming a single circuit from an inlet fitting to an outlet fitting.
Patent CA-2222842-A1 (CA)
Inventor: SHROFF DAVID N
IPC: E21B43/20
Filed: 1996-07-03
Abstract: A method of increasing the amount of hydrocarbons that are recoverable from an underground reservoir into which an oil well has been drilled. The method includes first pumping a quantity of negatively charged water down the oil well and into the underground reservoir. Then a quantity of particles of a copper-nickel-zinc alloy are pumped down the oil well and into the underground oil reservoir. Optionally the alloy is followed by a quantity of frac sand pumped down the well and into the reservoir and followed by a sufficient volume of negatively charged water to flush the frac sand out of the well casing and wellbore and into the reservoir. The well is then shut-in to stabilize the particles of alloy and frac sand, if added, within the reservoir. The well is then reopened, allowing the water and gases formerly entrained within the reservoir to be expelled from the reservoir and the well, thereby leaving the alloy particles and frac sand, if used, within the reservoir to provide a path for the continuing flow of hydrocarbons to the wellbore.

Abstract: Un bâton pour manipuler un anneau semblable à celui utilisé pour jouer à la ringuette et dont l'extrémité qui entre en contact avec l'anneau et la surface de jeu (la section de contrôle du bâton) comprend un butoir et/ou un talon et/ou une courbe. De façon générale, le butoir consiste en une surface plus ou moins verticale et le talon consiste en une saillie située sur l'extrémité du bâton. Essentiellement, le butoir ainsi que le talon servent à empêcher l'anneau de glisser vers le haut du bâton. Selon un mode de réalisation, la section de contrôle du bâton est courbée afin de prendre avantage de l'effet de levier. Le bâton peut également être conçu pour être bifonctionnel, c'est à dire qu'en plus d'étre utilisé pour piquer l'anneau, il peut être utilisé à la manière d'un bâton de hockey en le faisant pivoter sur son axe principal.

Title: Method and apparatus for providing an alternate telecommunications network
Inventor: GREENSPAN STEVEN LLOYD
IPC: H04M3/00
Filed: 1998-01-20
Abstract: A media selection device is in functional parallel with an alternate local telephone network and an existing local telephone network.  Upon detecting a loss of local power, the device switches to the local exchange network based on the assumption that the local exchange network is operable, despite the loss of local power.  While power is supplied to the device, originating calls are transmitted from the telephone to the device and to the alternate network.  Incoming calls from the alternate network are transmitted to the device and to the telephone. Alternatively, incoming and outgoing calls are also selectably engageable on the local exchange network without disrupting telephone service on the alternate network.  Differences in dial tone indicate which network is currently being used.

Title: Traffic shaper for network nodes and method thereof
Inventor: ELWALID ANWAR
IPC: H04L12/56
Filed: 1998-03-16
Abstract: The traffic shaping system according to the principles of the present invention increases the connection-carrying capacity of a network node by shaping the data cells to increase the admissible number of connections. In accordance with certain embodiments of the present invention, the traffic shaping system uses a data buffer at the ingress of the network node to selectively buffer classes of data cells. As such, the traffic shaping system exploits differences in delay tolerances between traffic classes to shape the less delay sensitive traffic classes to reduce the effective bandwidth of a connection of the particular traffic class and thereby increase the nodal connection-carrying capacity. Certain embodiments of the traffic shaping system operate within a framework to provide parameters for the traffic shaping system which increase the connection-carrying capacity for the node while meeting quality of service requirements for the data cells. In accordance with certain embodiments, an integrated regulator and shaper is provided which concurrently regulates and shapes the traffic cells to increase the nodal connection-carrying capacity.
