Title: Copy protection for hybrid digital video tape recording and unprotected source material
Inventor: RYAN JOHN O
IPC: G11B20/10
Filed: 1994-03-04
Abstract: A hybrid digital/analog video recorder prevents both analog and digital copying. The recorder (including a digital tape deck) inputs and outputs both analog and digital video signals. At the analog input, a detector detects conventional copy protection in the analog input video, and in response disables recording thereof.  At the digital input, a first detector detects anti-copy bits present in the input material and in response prevents recording.  A second bit detector detects serial copy prevention scheme bits, and in response adds an anti-copy bit to the input digital stream, preventing later copying of such material. When another bit detector detects anti-copy bits present in the playback digital data stream prior to conversion to analog, an analog copy protection signal modifies the output analog signal, inhibiting copying of the output signal. In another version, a specially adapted video recorder or playback device copy protects video source material which for technical reasons is not copy protectable.  A copy protect "flag" is provided in a predetermined location in the video signal to be protected. The video recorder or playback device, upon detection of the flag at playback, modifies the output standard (NTSC) video signal with a conventional copy protection  process.

Title: Electrically propelled vehicule
Inventor: BALL LARRY G
IPC: A63B55/60
Filed: 1995-10-19
Abstract: A method and  apparatus  for preventing overspeed of an electrically powered golf car having a shunt wound direct current electric motor with an armature  winding  and  a  field  winding  serially connected to respective switching devices and to a source of on-board direct current electric power. The  golf  car  includes  a  control  adapted  and connected to regulate the current in each of the armature and field windings for controlling speed in response to an operator's command.   The golf car incorporates  overspeed detection  by  sensing the magnitude of current in each of the armature winding and the field winding and detecting when the current in the armature winding reverses direction.   The magnitude of the armature winding current upon such reversal is compared to a preselected value and an overspeed signal generated when the reverse current magnitude exceeds the preselected value.  The field current  is then controlled,  in  response to the overspeed signal, to limit the speed of the golf car to inhibit the overspeed condition.  Additionally, the  voltage  at  the  motor  armature  winding is monitored during a time period when the motor is in a  non-energized  condition  and  a  motion  signal indicative of motor armature rotation is provided upon detection of a motor armature winding voltage. The motor field winding is energized, in response to the motion signal, with a voltage of a polarity for generating a field current to cause the motor to act as an electric  current generator and the current generated  by  the  motor  armature  is  circulated through a plugging diode and into the motor armature for electrically retarding rotation of the motor armature by plug braking.

Patent CA-2179668-A1 (CA)
Title: Esophageal Stent and Delivery Tool
Inventor: JOHNSON LIANN M
IPC: A61F2/966
Filed: 1993-03-10
Abstract: A radially self-expanding stent particularly suited for treating esophageal strictures, includes a medial region and proximal and distal cuffs having diameters greater than the medial region diameter when the stent is in the relaxed state.  A silicone coating circumscribes the medial region, but the cuffs are not coated and retain their open weave construction.  As a result, the cuffs remain particularly well suited to immediately contact esophageal wall tissue and resist stent migration, while the silicone coated medial region provides a barrier to tumor ingrowth, and has an enhanced radial restoring force to maintain an open passage-way in the esophagus.  A deployment device for the stent includes an interior catheter surrounded by the stent and having an esophageal dilation feature, along with an exterior catheter that radially compresses the stent. A low durometer sleeve, fixed to the interior tube and in surface engagement with the compressed stent, tends to fix the axial position of the stent relative to the interior catheter whenever the exterior catheter is moved axially relative to the inner catheter. Consequently, precision in stent placement and the ability to recapture a partially deployed stent are enhanced.

Title: Folding apparatus for transporting particulate material
Inventor: TOEWS ROBERT J
IPC: B65G41/00
Filed: 1997-02-10
Abstract: A conveyor for particulate material of the type including a tube with a belt running through the tube and defining a return run of the belt outside the tube provides a folding action by which the length of the tube can be reduced by folding an upper portion back against a lower portion. The folding action is actuated by a hand crank which drives a chain wheel connected to a pivot pin carrying the upper portion. The pivot pin is mounted to one side of the tube which is opposite to the return run of the belt. In order to provide an extension portion of the return run which can be released to provide the length necessary for the folding action, the return run passes over a pair of rollers to form a serpentine section of the return run at the fold line of the tube. Each of the rollers is carried on a respective one of the upper and lower portions on opposite sides of the fold line to release the serpentine portion as the folding action is effected.
