Title: A method and apparatus for downloading software into an embedded-system
Inventor: GARFUNKEL ARIE
IPC: G06F9/445
Filed: 2000-05-09
Abstract: Metliod for upgrading operating software and/or initialization program versions of an embedded system by using a single non-volatile memory.  The non-volatile memory comprises a write-protected area containing an original initialization and download operation program version, and an unprotected area containing an upgradable initialization and download operation program version.

Title: Apparatus and method for providing a high-priority service for emergency messages on a network
Inventor: HALASZ SYLVIA
IPC: H04L47/6275
Filed: 2000-07-25
Abstract: A network, such as the Internet, having a plurality of high-priority routers which permit emergency messages to be transmitted between terminals connected with the network. The routers each include a plurality of high-priority queues into which emergency messages designated as having a high priority are stored for immediate handling by the router. Each router also includes a regular priority queue in which data messages that do not include a high-priority designation are stored for handling by the router. Accordingly, when an emergency message having a high-priority designation is sent via the network, each router recognizes the priority of the data message and handles it in an expedited manner relative to the regular non-priority messages.  Thereby, the network can transfer emergency messages in an expedited manner for delivery at a receiving terminal.

Title: Method and assembly for separating formed constituents from a liquid constituent in a complex biologic fluid sample
Inventor: WARDLAW STEPHEN C
IPC: B01L3/00
Filed: 2000-08-18
Abstract: Formed constituents in an aqueous based fluid biologic material sample are separated from the aqueous constituent of the sample, and are concentrated in an examining instrument's focal plane where they can be examined under magnification. Examples of fluids that can be analyzed in this fashion include urine;  cerebrospinal fluid; pleural fluid; ascites; fluids aspirated from cysts such as thyroid and breast cysts; cytologic specimens which have been placed in an aqueous fluid; platelet-rich plasma; and the like. The sample is placed in a chamber having a layer of a hydrophilic hydrogel covering a surface of the chamber. An opposite surface of the chamber is transparent, and may be formed by a microscope slide cover slip, or the like. The volume of hydrogel in the chamber is sufficient so that, when the hydrogel absorbs essentially all of the aqueous fraction of the sample, the hydrogel will expand and fill the chamber. The capture surface of the expanded hydrogel is preferably planar, and any formed constituents in the sample will be captured on the capture surface of the hydrogel layer, and will not be absorbed into the hydrogel.  Formed constituents, such as: cells; bacteria; crystals; protozoa; ova; parasites;  and the like, can be differentially highlighted by use of labeled antibodies, selective stains, or the like, so as to enable optical examination and differentiation of various formed constituents which may be in the sample. Formed constituents may be harvested from the capture surface of the expanded hydrogel layer for more detailed examination and analysis. The capture surface of the hydrogel may be provided with a plurality of beads for use in locating the capture surface with an optical scanning instrument, and for re-establishing previously scanned fields of view.

Title: Latching mechanism for mounting plate of pedestal closure assembly
Inventor: DOLAN LAWRENCE SANTO
IPC: E05C19/06
Filed: 2000-08-22
Abstract: A latching mechanism for a pedestal closure assembly has a pair of substantially channel-shaped slots, each slot having two arms, a flanged base and first an d second ends. Each flanged base has a cam-like edge and is connected to the second end of each respective slot. The cam-like edge interconnects the upper and lower surfaces of the second end. A pair of legs adapted to be received by each slot are also included in the claimed  latching mechanism. Each leg has a limiting edge and includes an end portion adapted to limit the motion of the legs when they are received in the respective slots. At least one flexible latch arm adapted to engage the flanged base of at least one of the slots is connected to one of the legs. Each latch arm includes a finger element beyond the end portion of the  limiting edge of the leg. The finger element includes an engagement portion which abuts the lower surface of the flanged base of the leg when the leg is received in its respective slot.  The finger element has a cam-follower surface which bears against the cam-like edge of the slot  which flexes the latch arm allowing the engagement portion to move beyond the cam-like edge o f the flanged base of the slot so that the latch arm engages the flanged base. Thus, the slot is configured and dimensioned to slidingly receive each leg. The latching mechanism and th e pedestal closure assembly can be constructed of non-metallic material. Each leg of th e latching mechanism can contain a spacer bead and a transverse flange, each flexible latch arm can include an integral lip, and each slot can contain a guide rail. All of thes e are included to keep the legs more firmly secured in the slots when the latching mechanism i s engaged. Additionally, the pedestal closure assembly can have a service wire passagew ay with a channel slot which allows the internal equipment to be worked on without having to interrupt service and without having to unearth the lower housing section.

IPC: B65D67/00
Filed: 2000-10-18
Abstract: A device for protecting bows on gift-wrapped packages and the like. The device consists of two main components: a cup and a shield. The cup is of a type otherwise useful for drinking or eating ice cream from that has had its bottom portion cut into a number of pie-shaped segments all pointing to the center. The pie segments are flexible so that one can push the cup, bottom-first, over the bow to be protected, without harming the bow. Similarly, when the bow is to be displayed, the cup can be pulled back over the bow gently. The shield component extends across the otherwise open top of the cup, so as to provide protection against rain and other assaults on the bow from above. Operating together, the cup and the shield, when the device is slipped down over a decorative bow can protect the bow from becoming soiled or crushed, with special application to providing such protection when the package bearing the bow is wrapped for transportation, either across town or from one city to another. When the package is subsequently ready for display, the device can be readily removed from the bow and discarded or saved for another occasion.
