Title: Remote administration of hyaluronic acid to mammals
Inventor: SULTZ RICHARD H
IPC: A61P43/00
Filed: 1987-07-01
Granted: 1995-07-07
Abstract: The present disclosure is concerned with the discovery that hyaluronic acid, an agent well known to reduce the sequelae of trauma in mammalian joint tissue when applied directly to the traumatized tissue, will be carried to such traumatized tissue by the mammal's natural processes if applied at a site remote from the traumatized tissue. Thus, hyaluronic acid, in any therapeutically acceptable form, can be administered by the typical remote routes including intravenous, intramuscular, subcutaneous and topical. This makes the utilization of hyaluronic acid much more convenient and attractive. For instance the treatment of arthritis in horse or human joints with hyaluronic acid no longer requires more difficult intra articular injections.

Abstract: In an apparatus (1) for recording information signals (S) on a recording carrier (3) in tape form, an "information signal-controlled recording" operating mode can be switched on. For driving the recording carrier (3), the apparatus (1) has a motor (11) and a drive mechanism (12), which can be driven by the motor (11) and has two non- positively interacting drive parts (15, 16), which are constantly pressed against each other when the "information signal-controlled recording" operating mode is switched on, the motor (11) being switched on by a motor control circuit (43) if an information signal occurs, which is determined by an information signal detector (40), and is switched off after a time delay by the motor control circuit (43) if no information signal (S) occurs. The motor control circuit (43) has a pulse generating device (G) which, with the "information signal-controlled recording" operating mode switched on but no occurrence of information signals (S) for a considerable time, repeatedly generates at predetermined time intervals (T2) short control signal pulses (M1), by which the motor (11) is switched on for a short time, as a result of which the two drive parts (15, 16) are brought one after the other into always different relative positions with respect to each other.

IPC: G02F1/313
Filed: 1991-05-16
Granted: 1994-07-08
Abstract: In a digital optical switch which is based on the mode-selectivity principle, made up of a passive section (A) containing a first optical wave guide (1) and a second optical wave guide (2) and a switching section (B) containing a third optical wave guide (3) and a fourth optical wave guide (4), both the required asymmetry and the bringing of the optical wave guides within or outside each other's interaction region are achieved with the aid of curves (K1, K2) in said optical wave guides. In the switching section (B) said asymmetry is switchable. Use is made of the effect that a curve results, in general, in a reduction of the propagation constant in the optical wave guide. Suitable curves are of circular-arc shape and sinusoidal. The switching section (B) may furthermore incorporate a short intermediate section (s-u) in which the optical wave guides (12, 13) run straight at a small mutual angle ( PHI ) in the event that the switchable asymmetry is in the first instance too small with a particular choice of material. The invention makes possible much shorter switches which have a greater packing density. <IMAGE>

Title: Cursor generating circuit in camcorder
Inventor: KIM HYONG-KWON
IPC: H04N9/74
Filed: 1991-06-19
Granted: 1994-03-09
Abstract: The circuit has a pick-up for converting optical information about an object into an electrical signal. A video signal processor separates the picked-up signal into luminance and color signals. A filter filters only a high-band component of the separated luminance signal, and a converter changes the filtered signal into a digital signal. A detector receives the digital signal by predetermined picture intervals. The received signal is integrated by the sub-screens to detect the region having the largest integration. A motion forecasting device calculates the difference between a current signal output from the converter and a precedingly detected signal to predict the amount of movement of the object. A cursor generator variably designates the location of a cursor in the sub-screen to generate a cursor signal. A signal converter mixes the cursor signal and composite.
