Title: Methods and devices for draining fluids and lowering intraocular pressure
Inventor: QUIROZ-MERCADO HUGO
IPC: A61B19/00
Filed: 2004-02-18
Abstract: Methods, devices and systems for draining fluid from the eye and/or for reducing intraocular pressure. A passageway (e.g., an opening, puncture or incision) is formed in the lamina cribosa or elsewhere to facilitate flow offluid from the posterior chamber of the eye to either a) a subdural location within the optic nerve or b) a location within the subarachnoid space adjacent to the optic nerve. Fluid from the posterior chamber then drains into the optic nerve or directly into the subarachnoid space, where it becomes mixed with cerebrospinal fluid. In some cases, a tubular member (e.g., a shunt or stent) may be implanted in the passageway. A particular shunt device and shunt-introducer system is provided for such purpose. A vitrectomy or vitreous liquefaction procedure may beperformed to remove some or all of the vitreous body, thereby facilitating creation of the passageway and/or placement of the tubular member as well as establishing a route for subsequent drainage of aqueous humor from the anterior chamber, though the posterior chamber and outwardly though the passageway where it becomes mixed with cerebrospinal fluid.

This is achieved by a sealable mixing container (2) comprising a receiving chamber (7) for the pulverulent product (9) contained in the film sachet (8), the liquid and the optional additional component. The receiving chamber (7) is equipped with fitted components (6, 6'), which act mechanically on the film sachet (8).
Patent CA-2526412-A1 (CA)
Inventor: RICHIE JR WILLIAM S
IPC: G06K7/00
Filed: 2004-05-18
Abstract: A tracking system uses RFID (radio frequency identification) tag technology to facilitate the identification and tracking of items in an environment through a technique known as shadowing. As an object or target moves within a pre-described detection zone with communicating antenna and RFID sensors, the object or target blocks the line of sight between respective antenna and sensors, preventing electromagnetic coupling between the sensor and the antenna and thus casting an electromagnetic shadow along the line of sight.  One approach of this invention uses this shadow technique to perform functions such as theft (shrink) deterrence/ detection; tracking the motion of objects through an environment by monitoring the shadow; and correlation analysis of people shadows to tagged items (e.g., merchandise, articles) to foster marketing and merchandising effectiveness.

Title: Universal fixed pin trigger lock
Inventor: FARCHIONE THOMAS J
IPC: E05B73/00
Filed: 2005-12-09
Abstract: A firearm trigger locking device with two sides and fixed hardened steel pins.  The device is designed to be universal for a particular family of guns--e.g., all rifles, all shotguns, or all handguns (or all revolvers or automatic pistols)--of a given firearm manufacturer. The device further features a pin behind the trigger to prevent firing, hardened steel plates in each side sufficient in size to cover the trigger guard and prevent transverse application of a saw to the trigger guard, and a ring of hardened steel pins around the periphery of the trigger guard to prevent application of a saw between the plates. The method for producing this trigger locking device uses lateral and axial profiles of the family of firearms to develop features and feature locations that will allow it to be used with any member of the family of firearms.

Title: Replacement pad assembly for head immobilizer and cervical collar
Inventor: TRAUT JAMES
IPC: A61G1/04
Filed: 2004-07-15
Abstract: A base headboard for supporting the back of an injured person's head has an elongated slot with teeth racks disposed on either side of the injured person's head. The headboard also comprises straps for attaching to a spine board. Two side head blocks are removably attached to the headboard using plunger-type locks that engage an elongated slot on each side of a center portion of the headboard. Each lock is engaged to a slot of the headboard through a separate elongated slot in the corresponding head block.  Advantageously, a head block may be adjusted by moving the engagement of the lock along each independent slot in the headboard and head block, respectively. In addition, a head block may be rotated around its lock. Head pads and straps, and pads and straps for cervical collars that come into contact with a patient may be replaceable and packaged in a kit, thereby allowing the durable components (such as head blocks and headboard) to be reused indefinitely and reducing cleaning costs and minimizing exposure to pathogens. Such a kit of replaceable parts may also reduce material waste compared having all disposable components without any durable components (i.e.  head immobilizers).

Title: System and method for registering and unregistering membership in virtual local area networks
Inventor: FINN NORMAN W
IPC: H04L12/56
Filed: 2004-09-23
Abstract: A system and method efficiently conveys Virtual Local Area Network (VLAN) membership information across a bridged network. In particular, an intermediate network device, such as a bridge, includes a plurality of ports for interconnecting entities s of a computer network. For each port, a Generic Attribute Registration Protocol (GARP) participant is established that has a compact GARP VLAN Registration Protocol (GVRP) application component and a GARP Information Declaration (GID) component. The GID component operates a plurality of state machines to maintain registration state for all of the VLANs of which the port has been made aware. The compact- GVRP application component further includes an encoder/decoder unit that collapses VLAN  registration information according to an encoding algorithm. The collapsed VLAN registration information is then loaded into a single compact-GVRP PDU  message for transmission from the respective port. The encoder/decoder unit also recovers encoded VLAN registration from received compact-GVRP PDU  messages for operating the state machines.

Inventor: RADZINSKI PAUL
IPC: E21B47/12
Filed: 2006-04-10
Abstract: Disclosed herein is a borehole conveyance system that is conveyed within the borehole by a tubular such as a drill string. The conveyance system integrates wireline type downhole instrumentation into drilling and drill string tripping operations that are typically performed in a borehole drilling operation. This increases the types of measurements that can be obtained during the drilling operation. Equipment costs and maintenance costs can thereby be reduced. Certain wireline type tools can be used during drilling operations to yield measurements superior to their LWD/MWD counterparts and to reduce operation costs. Other types of wireline tools can be used to obtain measurements not possible with LWD/MWD systems. The rotation of the tool conveyance system and instrumentation therein is optionally controllable with respect to the rotation of the drill string by a selective locking subassembly (SLS)
