Title: System and method for managing device driver logical state information in an information handling system
Inventor: COOPER MICHAEL R
IPC: G06F9/445
Filed: 1998-03-09
Granted: 2003-07-22
Abstract: The present invention is directed to a system and method of managing logical device state information within an information handling system. Logical device state information is stored only once, by the information handling system. Device drivers do not need to maintain and store redundant copies of logical device state information. A device driver indicates whether or not it needs to have logical device state information passed to it. Before calling a device driver to handle a device function, the information handling system checks to determine whether or not the device driver has indicated that it needs logical device state information passed to it. If so, the information handling system passes the appropriate logical device state information to the device driver. For device functions which are not hooked by the device driver, the information handling system maintains the device state. System efficiency is increased, as each device driver may register for the subset of functions it can most efficiently handle, without hooking operating system functions or handling all state specific functions associated with a particular device function. In addition, device driver development may proceed in an incremental fashion, and device driver developers do not have to learn details of every operating system on which a device may be installed.

Title: Medical valve with tire seal
Inventor: LOPEZ GEORGE A
IPC: A61M39/02
Filed: 1996-12-16
Granted: 2007-02-13
Abstract: A medical valve has a body which includes a wall structure defining an internal cavity having a proximal end and a distal end. The proximal end has an opening sufficiently large to receive a tip of a delivery end of a medical implement which transfers fluid through the delivery end. The valve also has a spike with a tip contained within the cavity and at least one hole located distal the tip. The spike has a passageway in communication with the hole that allows fluid to flow through the spike. The valve also has a resilient seal in the cavity which surrounds the spike. The seal is adapted to be moved into a compressed state upon insertion of the tip of the medical implement into the opening. The seal is sufficiently resilient to return to a decompressed state upon removal of the tip of the medical implement from the opening. In addition, the seal has at least two tires in contact with the spike proximal the hole, preventing the flow of fluid through the valve when the seal is in the decompressed state.

The apparatus includes laser emitters (22) and receivers (24) for mouting in fixed relationship to the leading edge (36) of the blade (18) to provide a plurality of light beams (26) in advance of the blade (18). A controller (51) including halting means (57) for halting advancing movement of the blade in response to certain contingencies is provided. These contingencies include those involving interruption or obstruction of the light beams (26) and those which are indicative of a fault with the press or the safety apparatus itself. Accordingly the controller (51) also includes laser control and processing means (54), blade movement control means (56) and blade position processing means (58) which operate in conjunction with the halting means (57) to enable overriding control of the movement of the blade (18). The laser control and processing means further include pulsing means (55) to pulse the emitted light beams (26) in a unique manner so that each beam (26) can be differentiated from the others and also from ambient light sources. Vibration sensing means is also provided to enable discrimination between normal and abnormal vibration of the laser emitters (22) and receivers (24). The method involves use of mute point set a prescribed height above the material to be pressed whereby operation of the halting means (57) is associated with the position of the blade (18) relative to the mute point, whereby sensing of the laser beams for interruption or obstruction is muted after the blade (18) reaches the mute point. Different arrangements for setting the mute point are also described.

Abstract: A presentation system (50) is disclosed for distributing a performance of a presentation to a plurality of client sites (54) comprising client nodes on a network such as the Internet. The presentation system (50) distributes presentation content data to a plurality of network server nodes, and during a performance of the presentation, the client nodes receiving the presentation determine a particular variation of data presentation to retrieve from the network server nodes. In particular, the retrieval of presentation data depends upon the transmission characteristics of the network such as data transmission rate. Thus, if a low transmission data rate is detected at a first client node, presentation elements of a reduced size can be retrieved. Alternatively, if a higher transmission rate is detected at a second client node, presentation elements of greater size (and corresponding enhanced quality of presentation) can be retrieved. Thus, within a single performance, client network nodes with varying available network bandwidths can be utilized for synchronously performing the presentation.

Title: Total release actuator for an aerosol can
Inventor: DEMAREST SCOTT W
IPC: B65D83/16
Filed: 1998-05-11
Granted: 2006-01-10
Abstract: A total release actuator for use with an aerosol can having a chime (18), a dome (16), and a valve (24) having a valve stem (26). The actuator has an actuator body (28) with a lower margin defining a skirt rim (32) that attaches to the aerosol can and a central well (36) having a generally horizontal well floor that has a trigger port extending therethrough. The actuator has a trigger (48) that is hingedly attached to the actuator body, preferably at its front end (56) to the front end of the trigger port. The trigger swings downwardly when it is depressed. The trigger extends across the valve stem and includes a downwardly open stem socket (58) that receives the valve stem. The stem socket communicates with a discharge nozzle (60). The trigger, when moved downwardly, activates the valve, releasing the contents of the can through the discharge nozzle via the stem socket. A latch (62) is attached to preferably each side of the trigger port, extending laterally under the trigger. The latch is elastically deformable, allowing the trigger to pass as it is depressed downwardly and then springing back over the trigger to retain it in the depressed, valve-activating position, allowing can contents to discharge. By this means, a user can release the entire contents of the aerosol can without the user'shaving to continue to depress the trigger. A method is described of discharging the contents of an aerosol can by use of such an actuator.
