A multi-speed transmission suitable for automotive-type use employs paired helical gears. For each speed of the transmission, at least one pair of helical cut gears is mounted on an input drive shaft for engaging and mating at least one pair of helical cut gears mounted on an idler shaft. During load transmission for a given speed, the helical gear pairs on the idler shaft center themselves on the helical gear pairs on the drive shaft to balance load transmission amongst gears. The idler shaft would also have at least one pair of helical cut gears to engage and mate at least one pair of helical cut gears on a power output shaft.

An implantable medical device such as a defibrillator is described. The device includes an hermetically sealed housing containing a flat electrolytic capacitor and an energy source such as a battery. The battery is connected to the capacitor and provides charge thereto. The capacitor stores the charge at a relatively high voltage. The charge stored in the capacitor is discharged through a defibrillation lead to a site on or in the heart when fibrillation of the heart is detected by the implantable medical device. Methods of making and using the implantable medical device, the capacitor, and their various components are disclosed.

A surveillance system includes a track positioned along a selected path and a moveable carriage supported by the track. A pair of electrical conductors mounted adjacent and parallel to the track provide power to a drive assembly mounted on the carriage. Video cameras are mounted to the carriage for monitoring selected regions adjacent to the path. Output signals from the cameras are transmitted on the conductors to a remote monitoring location. In the preferred embodiment, control signals for controlling placement of the carriage along the track are also transmitted on the conductors.

An optical fingerprinting system includes an optics/processor unit, a video monitor, a data terminal, and a printer. The optics/processor unit includes a slap print prism for providing slap fingerprint images, and a plurality of individual finger prisms having differently sized finger-receiving grooves for providing individual fingerprint images. Slap/finger image selection optics selectively propagate fingerprint images from one of the individual finger prisms or slap print prism to a video camera. A video monitor is coupled to the camera, and provides a real-time display of the fingerprints being imaged. When a desired fingerprint image is observed on the monitor, an appropriate key of a key pad on the optics/processor unit is actuated and digital data characteristic of this image stored in memory. Following this procedure, data characteristic of all ten individual fingerprints and slap prints of both hands is stored. Demographic information of the person being fingerprinted is entered through the data terminal. The demographic information and fingerprint images can be printed at appropriate locations on a standard booking or applicant card.
