Patent CA-2137745-A1 (CA)
Inventor: STUTZ DAVID S
IPC: G06F9/54
Filed: 1994-12-09
Abstract: A method and system for dynamically generating object connections is provided. In a preferred embodiment, a connection can be generated between a source object and a sink object using a connection point object. A source object has connection point objects where each connection point object corresponds to a particular interface. A sink object implements one or more notification interfaces for connecting to a source object. A connection point object of a source object can connect to multiple notification interfaces, which belong to one or more sink objects. A connection point object keeps track of pointers to the notification interfaces to which it has been connected. In order to generate a connection, a sink object requests from a source object a connection point object corresponding to a particular interface. The source object determines whether it supports such a connection point object, and if so returns a pointer to the connection point interface of the determined connection point object. The sink object then requests to be connected to the connection point object using the returned connection point interface pointer and passes a reference to a notification interface of the sink object corresponding to the particular interface. The connection point object then stores the reference to the notification interface of the sink object, creating a connection between the sink object and the source object. At some later time, the source object can utilize the connection to notify the sink object through the connected notification interfaces.

Title: Method and apparatus for acquiring and processing subsurface samples of connate fluid
Inventor: MICHAELS JOHN M
IPC: E21B49/10
Filed: 1995-04-13
Abstract: A method and apparatus for downhole formation testing is provided for acquisition of a phase intact sample of connate fluid by direct or indirect pumping for filling of pressure containing sample tanks that are removable from a formation testing and sampling instrument for phase intact transportation to a laboratory facility. One or more fluid sample tanks contained within the instrument are filled with connate fluid samples in such manner that during filling of the sample tanks the pressure of the connate fluid is maintained within the predetermined range above the bubble point of the fluid sample. The sample tank incorporates an internal free-floating piston which separates the sample tank into sample containing and pressure evacuation chambers. During indirect pumping a positive displacement piston pump draws fluid from the pressure evacuation chamber and permits formation pressure to shift the separator piston as the first variable volume chamber is filled with a connate fluid sample.  The sample tank is provided with a cut-off valve enabling the pressure of the fluid sample to be maintained after the formation testing instrument has been retrieved from the well bore for transportation to a laboratory facility. To compensate for pressure decrease upon cooling of the sample tank and its contents, the piston pump mechanism of the instrument has the capability during direct pumping for increasing the pressure of the sample sufficiently above the bubble point of the sample that any pressure reduction that occurs upon cooling will not decrease the pressure of the fluid sample below its bubble point.

Title: Battery Pack Retention System and Apparatus Therefor
Inventor: MCCORMICK TIMOTHY P
IPC: H01M50/204
Filed: 1994-08-22
Abstract: The system includes a battery charger (300) and a battery pack (100). Upon insertion of the battery pack (100) into a retention area (303) of the battery charger (300), a battery pack channel (101) and a corresponding battery charger rail (305) align the battery pack electrical contacts (201) with the electrical contacts (309) of the battery charger. In order to ensure that a reliable electrical connection is made between the two sets of contacts (201, 309), a compliance rib (501) is disposed within the channel (101) of the battery pack (100). The compliance rib (501) creates an interference between the rail (305) and the channel (101), consequently, creating a force against the rail. The interference is calculated to create a sufficient force in combination with the force created by the weight of the battery pack (100) such that the force of the battery pack meets or exceeds the force created by the set of electrical contacts in the battery charger.
