Inventor: KHOSRAVI FARHAD
IPC: A61F2/92
Filed: 1994-04-22
Abstract: An intravascular stent comprising a cylindrical sheet having overlapping edges that interlock. The edges have a series of protrusions and apertures that interlock and ratchet as the stent expands to an open position to support a section of arterial wall. The stent may be expanded by a balloon catheter or it may be self-expanding. The stent is biocompatible, may be bio-erodible, and capable of localized drug delivery. A plurality of retaining members to keep the stent open are disclosed. In one embodiment a buckle fastening member is used, while in another embodiment a helical seam containing projections is employed. The stent may be wound in such a manner that during expansion of the stent, one side of the sheet comprising the stent desires to return to its original shape, creating a bias. In addition, a variety of reticulated structure stents are disclosed, with novel geometric patterns that aid in increased flexibility while preserving radial strength and which also allow blood-tissue interaction and side branch access. The intravascular stent may be made of a sheet of material strengthened and stiffened by pyrolytic carbon or by structural reinforcement as in composite laminates.

Title: Transcription adaptors in eukaryotes
Inventor: GUARENTE LEONARD
IPC: C12N15/67
Filed: 1992-11-18
Abstract: The present invention relates to a protein or protein complex which stimulates activated DNA transcription in eukaryotic cells, genes encoding the protein or proteins, and uses therefor. The protein or protein complex, referred to herein as a transcriptional adaptor, is associated with two other factors, each of which, in turn, binds to a region of a eukaryotic promoter. The first of these factors, referred to herein as an activator, binds to a region of the promoter DNA sequence termed the UAS binding site or enhancer. The second factor or factors, referred to herein as a general transcription factor (GTF), binds to second region of the promoter DNA sequence, termed the TATA box, which is located downstream from the UAS binding site. The transcriptional adaptor specifically binds to an acidic activation domain (i.e., one which is highly enriched in acidic amino acids, such as aspartic acid and glutamic acid) on the activator protein which, in addition, includes a DNA binding domain.

Filed: 1994-08-18
Abstract: A method and system for maintaining a routing path between a selected workstation within a multisegment local area network and a mobile workstation wherein individual segments within the multisegment local area network are interconnected by a router device  and wherein selected segments within the multisegment local area network include radio frequency transceivers adapted to provide a wireless communications link with mobile workstations.   Each time communication is established between a mobile workstation and a selected workstation within the multisegment local area network via a radio frequency transceiver a routing table  entry  is  established which  identifies  a  segment location for the mobile workstation within a routing table associated with each router device within the multisegment local  area  network.    A  routing  table  entry  is  also established which identifies a segment location for the selected workstation within  the routing table associated within each router device within the multisegment local area network in response to each attempt at establishment of communication between  the  selected workstation  and the mobile workstation.  Thereafter, all routing table entries which identify the segment location for a mobile workstation are automatically deleted in response to a termination of communications between the mobile workstation and the radio frequency transceiver.   Routing path determination  for communications  between  a  mobile  workstation  and  any workstation within the multisegment local area network may then  be  determined by  reference  to  a  routing  table associated with each router device within a multisegment local area network without requiring the maintenance of routing path information at each workstation within the multisegment local area network.

Title: Motorized binding machine
Inventor: CRUDO PHILLIP M
IPC: B42B5/08
Filed: 1993-08-27
Abstract: The present invention relates to a machine for binding sheets together with plastic strips. The machine compresses two strips, one strip (21) having studs extending therefrom and another strip (24) having holes corresponding to the studs, towards each other, then cuts off the ends of each stud and forms rivet heads thereon to bind the sheets together. The improvement over such machines uses a motor (201) to drive linkages previously manually actuated. The binding motor (201) drives linkages (81, 67 and 221, 232) on either side of the machine which causes a transverse pressure bar (61) to apply a pre-selected force on the strips, then to initiate movement of a knife (122) which cuts off the studs and form heads thereon and finally release the compressive force. A second motor (216) drives a linkage (218, 219, 221) which returns the pressure bar to its upward position as the binding cycle is completed.

Patent CA-2156538-A1 (CA)
Inventor: CRUMP DWAYNE T
IPC: G06F1/32
Filed: 1995-08-18
Abstract: A computer system having four states of power management: a normal operating state, a standby state, a suspend state, and an off state. A control unit controls transitions between the various states.  The standby state is characterized by devices, such as a video controller and a hard drive, being placed into a low-power mode transparent to the operating system and the applications executing on the computer system.   The suspend state is characterized by executing code being interrupted and the state of the computer system being saved to a file on the hard drive in such a manner that system power may be removed after the state of the computer system is saved to the hard drive.  Later, after system power is restored, the state of the computer system is resumed by reading from the hard drive and loading it in such a manner that the operating system and application programs are not adversely affected.   The normal operating state and the off state correspond to the typical on and off states of more conventional computer systems.  A single switch causes transitions between the various states.  A visual feedback device, such as an LED is used to indicate the state of the computer system.   While no power management driver is active,  the control unit delays  state  transitions until a suitable power management driver is active.
