Title: System and method for testing adequacy of human hearing
Inventor: ZUREK PATRICK M
IPC: A61B5/12
Filed: 1993-04-08
Abstract: Disclosed is a system and method for measuring hearing in which multiple single-frequency tones are presented by each of two transducer (64, 66), each transducer presenting only one single-frequency tone. One transducer is employed to present a plu-rality of f1 primaries, each in a different location of the range of audible frequencies, and the other transducer a plurality of corresponding f2 primaries, each having a frequency with respect to its corresponding f1 so as to make the ratio of frequen-cies suitable for the production of EDPs by that pair. By selection of an appropriate frequency far each primary in each set, a plurality of pairs may be presented to the ear simultaneously, without encountering the problems caused by the presence of numerous intermodulation products due to the interaction of the multiple primaries issued by the same transducer. This allows a single test to be performed that will simultaneously provide information about hearing function over a range of au-dible frequencies.

Title: Motorized dynamic traction device
Inventor: SCHENCK ROBERT R
IPC: A61H1/02
Filed: 1994-10-13
Abstract: ABSTRACT OF THE DISCLOSURE In accordance with the present invention, there is provided a portable hand mounted device for tractioning a finger having a fractured bone and at the same time continuously flexing and extending the joint to which the fractured bone is proximally attached in order to prevent joint deterioration.  More particularly, the device may be made in an inexpensive manner by medical personnel and is a light, less cumbersome device than that in the prior art.  A drive motor is carried by a cast-like support which is attachable to the forearm and hand for substantially immobilizing the wrist joint and joints of the hand proximal to the joint which is immediately proximally connected to the broken bone.  The support carries a frame or hoop defining a substantially arcuate path of motion for carriage travel while flexing and extending the joint of the fractured finger.  The carriage rides on the hoop first in one direction and then in the other direction along the arcuate path.  The carriage is driven by an elongated, flexible yet stiff cable mounted for travel in a guide in the hoop with one end of the cable connected to the drive motor to push and pull the cable in the groove and to reciprocate the carriage.  Elastomeric bands tension the broken finger to the carriage so that the finger joint follows the reciprocating carriage to first extend the finger, bending occurring primarily at the proximally connected joint.

Abstract: A process for the permanent destruction of unwanted human hair. Hair duct in a section of skin in which the unwanted hair is growing is contaminated with contaminant comprised of a very large number of small particles having a high absorption at at least one frequency band of light. The skin section is then illuminated with a series of short pulses of light at the frequency band of high absorption, the first of said short pulses having sufficient energy to cause a large number of the particles to explode into two or more fragments so as to spread said contaminant in said hair ducts and subsequent pulses having sufficient energy to cause a large number of the fragments to further explode into additional fragments to further spread the contaminant in the hair duct, the explosions and energy transferred to and from said particles and fragments causes damage to skin tissue surrounding said hair ducts so as to cause death to the hairs growing in the ducts. In a preferred embodiment the particles are 1 micron graphite particles and each section is illuminated with about 5 laser pulses at 1.06 micron wavelength produced by a Nd:YAG laser, each pulse having an energy density of about 3 Joules/cm2 and a pulse width of about 10 nano seconds.

Inventor: GROVES GILLIAN K
IPC: G01S3/786
Filed: 1995-01-25
Abstract: A method (30) for measuring and quantifying clutter, and target detection and tracking systems (10) that employs wavelet-based clutter quantification to generate a clutter number and a signal-to-clutter ratio derived therefrom to achieve improved target detection performance. The method (30) processes video signals representative of an image scene (14) containing a target (15) and background clutter (16) to provide for more accurate tracking of the target (15) by a tracker(s) (21). The method (30) comprises processing (31) the video signals to compute a wavelet clutter number,processing (32) the video signals to compute a signal-to clutter ratio using the wavelet clutter number, and generating (33) a pointer to a lookup table that sets parameters and selects the tracker (21) that is to be used to track the target (15) based upon the computed signal-to clutter ratio. The target detection and tracking system (10) tracks a target (15) located in an image scene (14) containing clutter (16). The system (10) comprises a sensor (11) for generating video signals representative of the image scene (14) that contains the target (15) and the background clutter (16). A tracking computer (12) is coupled to the sensor (11) that comprises a tracker(s) (21) that implement predetermined tracking algorithms that are designed to track different types of targets (15). A wavelet-based signal-to-clutter processor (20) is coupled between the sensor (11) and each of the tracker(s) (21) for processing the video signals to compute the wavelet clutter number and the signal-to clutter ratio using the wavelet clutter number, and for generating a pointer to a lookup table that sets parameters and selects a particular tracker (21) or tracking algorithm that is to be used to track the target (15) based upon the computed signal-to clutter ratio. A display monitor (13) may be coupled to the tracker(s) (21) for viewing the tracked target (15) and the image scene (14). The computed signal-to clutter ratio corresponds to target contrast divided by the clutter number, where the contrast is defined as the difference between a peak gray level (P~) of the target (15) and a local background gray level (µb).
