Cordless power system

A cordless system has cordless system components that include a cordless device, such as a cordless power tool, a battery pack and a charger. The battery pack is mated with either the cordless device to provide power to operate the cordless device or to the charger to charge the battery cells in the battery pack. In an aspect, the cordless system has an identification and communication system by which the battery pack identifies and communicates information about the battery pack to the cordless device or to the charger to which the battery pack is mated. In an, the battery pack of the cordless system is capable of multiple modes, such as controlling the cordless device and controlling the charger. In an aspect, the battery pack validates the cordless device or charger to which it is mated in an aspect of the invention, the cordless system uses any of a wired interface, radio frequency interface, an optical interface or a magnetic interface to communicate information between the battery pack and the cordless device or charger to which the battery pack is mated. In an aspect, female terminals are used in a terminal block of the battery pack to protect against foreign objects contacting the terminals. In aspect, the terminals in the terminal block of the battery pack are staggered or scattered to reduce the likelihood of a short circuit. In an aspect of the invention, the battery pack has a trap door that closes when the battery pack is not mated to a cordless device or charger to protect the terminal block of the battery pack. In an aspect of the invention, multi-spring, split contact terminals are used in the terminal block of at least one of the cordless system components. In an aspect of the invention, the battery cells are Lithium Ion battery cells.

Remote augmented motor-sensory interface for surgery

A portable augmented motor-sensory interface (“PAMI”) system for “tele-controlled” surgery includes a PAMI tele-controller and a portable PAMI medical field unit positioned at a different, distant location and configured for wireless communications with the tele-controller. (“Tele-control” refers to electronically translating and/or transmitting a physician's actions over a long distance.) The field unit has a surgical module, including robotic effectors/arms, configured for carrying out medical procedures, and a video sensor boom for electronically viewing a wound site. The tele-controller has a user interface with input controls and a display that outputs sensory information relating to the patient and field unit. For treating a patient, the field unit is deployed next to the patient and a communications link is established to the tele-controller. A physician at the tele-controller receives sensory input from the field unit through the user interface display, and manipulates the input controls for tele-controlling the surgical module.

Inertially controlled switch and RFID tag

One or more inertially controlled switches may be coupled to a radio frequency identification (RFID) tag, so that the response of the RFID tag indicates the state of the switch(es). The RFID tag and the switch(es) may be coupled together in various ways so that the state of the switches affects the response of the RFID tag to an RFID reader.

Weapon and input device to record information

The system of the preferred embodiments includes a weapon, an input device coupled to the weapon and adapted to record information, a memory device coupled to the input device and adapted to store recorded information, and a security device coupled to the memory device and adapted to inhibit unauthorized tampering of the recorded information. The system has been specifically designed to record information during the use of a weapon. If used properly, the recorded information should increase the accountability of army personnel and police officers.

Piston-actuated endoscopic steering system

Endoscopic steering apparatus is provided, including an endoscope (80) having distal (82) and proximal (98) ends thereof. In a preferred embodiment, at least one proximal cylinder (92) is disposed in a vicinity of the proximal end of the endoscope, and at least one proximal piston (94) is slidably coupled to the at least one proximal cylinder. This piston is typically manually driven. A first distal cylinder (88) is disposed at the distal end of the endoscope, and a first distal piston (90) is slidably coupled to the first distal cylinder. A second distal cylinder (88) is disposed at the distal end of the endoscope, and a second distal piston (90) is slidably coupled to the second distal cylinder. A first tube (86) is coupled to the first distal cylinder and to the at least one proximal cylinder, and a second tube (86) is coupled to the second distal cylinder and to the at least one proximal cylinder. A linkage (96) is disposed at the distal end of the endoscope and coupled to the first distal piston and to the second distal piston, such that displacement of at least one of the distal pistons causes displacement of the linkage and steering of the distal end of the endoscope.

Retractor for performing heart and thorax surgeries

A retractor has a rail, a first holding arm protruding from this rail at an angle at a second holding arm extending approximately parallel to the first holding arm. A distance between the two arms being modifiable. At least one functional element is mounted on one of these holding arms, which functional element has a section extending transversely to the holding arms and a swivel bracket protruding from this transverse section. The functional element being pivotable about a pin extending roughly parallel to the arms via the swivel bracket, a swiveled position can be set by grasping the function element with a hand. A locking mechanism serves for locking the functional element in a swiveled position.

Signal processing apparatus

The present invention involves a method and an apparatus for analyzing measured signals, including the determination of a measurement of correlation in the measured signals during a calculation of a physiological parameter of a monitored patient. Use of this invention is described in particular detail with respect to blood oximetry measurements.

System and method for audio and video portable publishing system

A system that allows consumers to manage content and create audio/video presentations in a small portable media device, and to share media files with other users of small portable media devices, without requiring access to a computer.

Ablation catheter

Devices, systems and methods are disclosed for the ablation of tissue. Embodiments include an ablation catheter which has an array of ablation elements attached to a deployable carrier assembly. The carrier assembly can be constrained within the lumen of a catheter, and deployed to take on an expanded condition.

Decommissioning an electronic data tag

Rendering data stored within an electronic data tag unreadable. A receptacle receives an article with the data tag, detects the presence of the electronic data tag, and decommissions the electronic data tag. The receptacle further modifies a label on the article to remove data printed thereon.
