Abstract: A color-changing, position-reversible hourglass assembly having two transparent bulbs one above the other and a storage compartment adjacent each bulb, the bulbs and compartments being joined together by a neck.  Intercoupling the bulbs and the compartments is a crossover network which passes through the neck to couple each bulb to the compartment adjacent the other bulb.  In operation, when one bulb and its adjacent compartment are in an up position and are respectively loaded with sand of different color, then sand of one color appears to trickle from the up bulb into the compartment in the down position while sand of another color appears to trickle from the up compartment into the down bulb.  The resultant apparent flow of sand from a higher to a lower level creates the illusion that sand flowing out of the up bulb is undergoing a color transformation as it flows into the down bulb.

Title: Rare earth element-doped multiple-core optical fiber and optical systems using the same
Inventor: IMOTO KATSUYUKI
IPC: G02B6/036
Filed: 1996-08-07
Abstract: A rare earth element-doped multiple-core optical fiber has a bundle of cores co-doped with Er and A1, primary cladding layers covering each core, and an outer cladding layer covering all cores, wherein one core is positioned substantially on a central axis of the outer cladding layer and surrounded by the remaining cores.

Abstract: The loopback test consists of a user-application interface that connects the network operator to substantially all of the ATM points in the network. In operation, the network operator selects two ATM points as the loopback and source endpoints for the loopback test.  The virtual path identification (VPI), virtual channel identification (VCI) and payload type indicator (PTI) that will be in the address header of the test cell when it arrives at the loopback endpoint location and the identification of the loopback endpoint are transmitted to the loopback endpoint in a setup message via a link from the UAI.  The VPI, VCI and PTI that constitute the address header of a test cell injected at the source endpoint and destined for the loopback endpoint, and the location identification of the source endpoint are provided to the source endpoint in a setup message via a separate link from the UAI.  The source endpoint formats a test cell based on this information and injects the cell into the network where it is routed based on the address header. The targeted loopback endpoint monitors the node identified in the setup message anticipating the arrival of the test cell.  When the test cell arrives, it is captured by the loopback endpoint, examined to ensure that it is the appropriate loopback cell and retransmitted to the source endpoint.

Title: Articulated arm for medical procedures
Inventor: NG WAN SING
IPC: A61B90/50
Filed: 1995-06-20
Abstract: An articulated arm is disclosed which can be used to firmly support and position a variety of medical tools, including surgical or diagnostic instruments flexibly in space. Though some of its sub-assemblies may be computer controlled, thus autonomous in accordance to some pre-programmed sequence, manual control is also possible. When its sub-assemblies are suitably controlled using computer software, and with a suitable cutting instrument, the arm is capable of generating a barrel shape cavity or, for that matter, any desired shape of cavity (or treatment volume) that is within the work envelope of the arm. The ideal position of the focal point is dynamically variable as required, either with respect to the tool or the absolute frame of reference, during an intervention. A suitable type of intervention is minimally invasive surgery (MIS). Apart from cutting (or resection), the articulated arm, by virtue of its robotic nature, can also be used to perform such tasks as biopsies and radiation seed implantation, where positional accuracy and repeatability are highly desirable. The articulated arm is a universal computer assisted holder for a wide range of medical tools, in particular endoscopes for treatment of urological disorders.

Title: Surgical Devices for Imposing a Negative Pressure to Stabilize Cardiac Tissue During Surgery
Inventor: TAYLOR CHARLES S
IPC: A61B17/02
Filed: 1997-02-14
Abstract: The invention is devices and techniques which use a negative (suction) pressure or vacuum, applied through a surgical instrument, to fix the position of a portion of the surface of a beating heart so that a surgical procedure can be more easily performed. The devices apply a negative pressure at several points on the outer surface of the heart such that a portion of the heart is fixed in place by the suction imposed through the surgical instrument. Because the instrument fixes the position of the tissue, and because the instruments remain at a constant distance from the particular portion of the heart where the surgery is being performed, the device may also serve as a support or platform so that other surgical instruments or devices can be advantageously used at the site. In certain preferred embodiments, the devices described herein have structures to facilitate the use of additional surgical instruments such that the placement of negative pressure device permit the surgeon to advantageously manipulate the other instruments during surgery. The negative pressure is preferably imposed through a plurality of ports which may be disposed in a substantially planar surface of the instrument which contacts the cardiac tissue.

IPC: C07K16/18

Abstract: The present invention provides a Bcl-2-interacting protein. This Bcl-2-interacting protein has been purified and shown to be identical to a previously described 28 kDa protein (p28) called Bap31 /CDM. Human p28 is a polytopic integral protein of the endoplasmic reticulum (ER) whose cytosolic domain contains overlapping death effector domain and leucine zipper homologies, flanked on either side by identical caspase recognition sites. Following apoptotic stimuli in the absence of Bcl-2, p28 was cleaved at both caspase recognition sites. One of the cleavage products, p20, caused induction of apoptosis when expressed ectopically in otherwise normal cells. All of these events were prevented by elevated expression of Bcl-2. p28 Bap31 may be a Bcl-2-regulated component of an apoptosis signaling pathway, perhaps involving coordinated ER-mitochondrial events. P28 Bap31 itself or the cleavage of p28 Bap31 and the cleavage products thereof are useful in diagnostic kits, laboratory reagents, assays and development of reagents for the treatment of disease relating to apoptosis.
