Patent CA-2289343-C (CA)
Inventor: BORKOWSKI ANDRZEJ
IPC: F04B49/10
Filed: 1999-11-09
Granted: 2005-08-16
Abstract: An apparatus and method is provided for automatic shut-off of a combustion engine driving a fluid pump of a fluid displacement unit in order to protect the fluid displacement unit from damage due to excessively high running speeds. The apparatus includes a latching circuit that trips when an attention electrical signal exceeds a shut-off threshold potential. A biased electrical switching component inhibits fuel ignition for a period of time allowing the engine to spin down to rest. The latching circuit and switching component thus prevent the engine from being flooded to which prior-art devices are prone when their mechanical latches are not reset. Furthermore, this apparatus and method saves the engine from overspeeding damage to which prior-art devices are prone when a user blocks the mechanical latching action.

Abstract: A method and apparatus remotely accesses a user's caller identification system using existing caller identification systems and standard telephony systems by capturing telephone call origination information from a telephone call, storing the origination information in a compute network file system, and displaying the origination information to a user either via a World Wide Web site, transmitting it to the user's email account, thus automatically informing the user of an incoming call, or making it available to the user via a telephone interface device that responds to input from the user either via touch tones or voice. The user is able to manage the contents of the user's call-log using a web-browser. The end result is that users are able to view their office telephone activity logs form anywhere in the network, using a web browser, which is much more convenient than checking voice mail.

Abstract: Activating a switch by a handset where the switch is manually activated when the user wishes to answer an incoming call. While the switch is in the deactivated state, the handset transmits to a sound card within a personal computer a multi-frequency tone which is detectable by the sound card. When the manual switch is activated, the handset ceases to transmit the multi-frequency tone to the sound card. The sound card detects the absence of the multi-frequency tone to determine if the handset is answering a call. In traditional telephony terms, when the manual switch is activated, this is the offhook condition. When the manual switch is deactivated, this is the onhook condition. When the user is done with the call and deactivates the manual switch, the handset again generates the multi-frequency tone that is subsequently detected by the software via the sound card. Then, the software knows to signal the other party on the call that the call has been terminated. A headset is similarly designed to provide the same multi-frequency tone generation features as the handset.

Granted: 2007-12-04
Abstract: A metal oxide ceramic material such as alumina or chromia which has been rendered electrically conductive through its thickness by the incorporation of silver into the material. The metal oxide ceramic material may be in the form of a layer on a substrate such as a bipolar plate or other component for a fuel cell assembly. The electrical conductivity may be achieved by heating the ceramic material and a silver-containing material in contact with each other to at least 750 °C such that silver migrates from the silver-containing material into the metal oxide ceramic material and creates electrically conductive pathways through the ceramic material. In a particular embodiment, the substrate is a steel which forms an alumina, chromia or alumina-rich or chromia-rich surface layer in oxidising atmosphere and the silver-containing material is heated in an oxidising atmosphere in contact with the steel to cause the surface layer to form on the steel and to cause silver from the silver-containing material to occur in and create the electrically conductive pathways through the layer. The silver-containing material may be commercially pure silver or other forms of silver.
