Keyed self-latching battery pack for a portable defibrillator

A battery pack (28) for a portable defibrillator (30). The battery pack has a latch (34) that is biased in an extended position. When the battery pack is inserted into a battery well (30) in the portable defibrillator, the latch automatically latches into a slot (124) to secure the battery pack in tile battery well. Ridges (112) are provided on the floor (108) of the battery well to reduce the friction between the battery pack and the floor of the well as the battery pack is inserted into the defibrillator. A ridge (38) is also provided around the periphery of the top (36) of the battery pack to reduce the friction between the battery pack and the ceiling of the battery well. A right wall (44) of the battery pack is inclined from vertical so that a cross section of the battery pack is trapezoid in shape. The asymmetric cross-section prevents the battery pack from being incorrectly inserted into the battery well. The disclosed battery pack construction simplifies the replacement of the battery pack in the portable defibrillator.

Multi-component vascular device

A vascular occlusion, flow restriction, shunt or filter device is disclosed comprising the assembly of at least two, of a number of selectable discrete interconnectable, interchangeable components, at least one component being of the type fabricated from metal strands braided into a tubular metal fabric having an expanded preset configuration and an elongated, collapsed reduced diameter configuration for delivery through a catheter to a treatment site and the device shaped to create an occlusion, flow restriction or shunt when placed in an opening in a body organ or vessel, the woven metal fabric having a memory property whereby the medical device tends to return to said expanded preset configuration when unconstrained.

Fiber optic device for sensing analytes and method of making same

A device for sensing analyte concentration, and in particular glucose concentration, in vivo or in vitro is disclosed. A sensing element is attached to the distal end of an optical conduit, and comprises at least one binding protein adapted to bind with at least one target analyte. The sensing element further comprises at least one reporter group that undergoes a luminescence change with changing analyte concentrations. Optionally, the optical conduit and sensing element may be housed within a cannulated bevel.

Personal choice biometric signature

A biometric method and system for personal authentication using sequences of partial fingerprint signatures provides a high security capability to various processes requiring positive identification of individuals. This approach is further enhanced by employing a frequency domain technique for calculating a Similarity Index of the partial fingerprint signatures. In a baseline usage, the sequential partial fingerprint sequence techniques augments sentinel systems for gaining access to restricted areas, and when used in combination with financial cards, offer a unique and greatly simplified means for authenticating or identifying individuals. A highly automated technique initially obtains four (illustratively) linear partial fingerprint signatures which serve as reference data against which later proffered candidate data in the form of at least two linear partial fingerprint signatures are compared for authentication. The particular two candidate signatures used and the sequence in which they are submitted are selected with the user's consent and serve as a PIN-like unique personal code. In an advanced embodiment, the same two candidate signatures in the chosen sequence are processed in a unique FFT / DFT process to produce a highly reliable Similarity Index to authenticate or verify the identity of individuals. The use of only partial fingerprint data greatly allays the concerns of widespread fingerprint dissemination by many individuals.

Fully-automatic mahjong machine

The invention relates to a fully-automatic mahjong machine comprising a board sending system, a board loading system, a board lifting system and a large shuffling disc. The board sending system comprises four board sending mechanisms, each board sending mechanism comprises a transmission rack, and a board sending motor, a board absorbing wheel, a transmission belt, a transmission platform, a board inlet guiding piece and a board outlet guiding piece fixed on the transmission rack; a board sending channel is arranged at the upper end of the transmission platform, the board absorbing wheel is tightly attached at the lower end of a board inlet opening of the board sending channel, the board inlet guiding piece is positioned above the board absorbing wheel, the board outlet guiding piece is positioned at a board outlet opening of the board inlet channel, the board sending motor is used for driving a motor guiding wheel, the motor guiding wheel is positioned below the transmission platform, and the transmission belt loops the motor guiding wheel, the board absorbing wheel and the transmission platform. In the invention, for the mahjong boards with different widths, the board sending mechanism of the mahjong machine can run normally by only replacing the corresponding board inlet guiding piece and the board outlet guiding piece, and a transmission rack cover does not need to be changed, so that the operation is simple and convenient, and the board inlet guiding piece and the board outlet guiding piece has extremely low production cost relative to the transmission rack cover.

Patient specific anatomically correct implants to repair or replace hard or soft tissue

The present invention relates to a system of preparing a one of a kind artificial or biological implant to repair or replace a bone or a tissue part in a living individual, the system comprising: pre-operatively constructing an anatomically correct, affected area 7-unique scan implants geometry, wherein the implants geometry is unknown before the acquisition of the individual's data; and using a process derived from rapid prototyping to construct a geometrically and anatomically correct duplication of the functional attributes of the bone or tissue part to be replaced from the dataset created by scans of the recipients scans. This system can also be used to modify, pre-operatively, existing FDA approved implants.

Counter top reverse osmosis water purification system

A counter top reverse osmosis water purification system, suitable for home use, is connected to a water supply and contains a closed fluid treatment circuit extending to a water outlet. The closed fluid circuit flows through a plurality of replaceable water treatment modules mounted on a flowboard and each having a specific water treatment function, such as the removal of a particular material from the water by the use of reverse osmosis, filtration, carbon adsorption, ion exchange or the addition of a chemical to balance the desired water conditions. Preferably the circuit also includes traversing a radiation device, for example an ultraviolet light, for the purpose of sanitizing the water.
