Patent CA-2048852-A1 (CA)
Inventor: ORTIZ PEDRO R
IPC: G03G15/00
Filed: 1991-08-08
Abstract: Productivity in electronic printer incorporating finishing activities and operating in a job streaming mode is enhanced by utilizing software to calculate and predict the minimum delay (measured in skip pitches) in successive jobs requiring finishing activities such as binding and stapling. Printing and collating of sets of original scanned documents are controlled so that collated sets are successively presented by the printer to the finishing means nearly coincident with conclusion of the finishing activity being accomplished for a current job. Additional software innovations allow job scheduling for jobs involving complex pitch time delays created by scanning simplex and duplex documents returned in random order. For this case optimum delay time is the cumulative finishing hardware delays as well as imaging/paper path delays. Still another feature is a predictive algorithym which is used to increase reliability of printer components by cycling down the printer between jobs in situations where the finishing activity for a current job requires an extraordinarily long time to complete compared with the cycle down/cycle up time of the printer.

Title: Cervical videoscope with detachable camera unit
Inventor: ADAIR EDWIN L
IPC: A61B18/24
Filed: 1992-04-14
Abstract: A simple yet highly useful cervical videoscope has been provided which can easily be used by the doctor to examine the cervix and vagina far cancerous lesions or other abnormalities. Also, because of the small size of the video camera unit there is sufficient space between the video camera unit and the blades of the speculum for inserting forceps and other instruments that may need to be used. By using the cervical videoscope in combination with a monochromator the physician can step the wavelength of light from one end of the light spectrum to the other until he observes florescence which identifies abnormal cells. Thereupon, he can destroy the cells by use of a laser beam. When he observes that no more florescence is occurring, then he can discontinue the operation of the laser, knowing that the lesion has been completely eradicated. Also, a channel for drawing a suction to remove smoke created by the destruction of the lesion can be provided. The video camera unit also is adjustable along a guide on the fixed blade of the speculum to focus it. The video camera unit can be removed from the speculum and inserted into a sterile sheath for reinsertion into the vagina for examination for lesions and areas covered by the speculum blade. It can also be inserted into the colon and other body passageways where lesions are suspected. The video camera unit can be removed from the sheath, resterilized or disinfected and reattached to a sterile speculum for use with another patient.

IPC: H04W88/02
Filed: 1992-05-19
Abstract: MAXIMUM LIKELIHOOD SEQUENCE ESTIMATION   BASED EQUALIZATION WITHIN A MOBILE      DIGITAL CELLULAR RECEIVER         ABSTRACT The present invention provides for an equalization method that forms the nucleus of a receiver for digital cellular mobile telephones. A number of distinct aspects of the design are considered novel, including non-real time operation that permits and exploits "time-reversed" equalization to significantly enhance bit error rate performance. The present invention employs the use of a maximum likelihood sequence estimation process. It uses variable coefficient least mean square tracking during estimation of the transmission channel's impulse response. It also employs the use of integrated symbol timing adjustment and carrier tracking algorithms. Time-reversed operation further enhances performance and permits implementation with reasonable complexity of a standards compliant mobile receiver.

Title: Toy glider with launching unit
Inventor: WONG CHEUK-YAN C
IPC: A63H27/00
Filed: 1992-05-22
Abstract: Toy Glider with Launching Unit Abstract A toy glider system consists of a toy glider and a regular hand launch-ing unit, mainly for outdoor use, or a launching platform, for both indoor and outdoor use. The inventions of this system are the simple but effec-tive triangular or "delta" wings and the aileron structure of the glider; and the holding, guiding, and accelerating mechanisms of the launching platform. The special wing structure of the glider allows the glider to have the high-speed characteristic when it is released from the launching unit. Hence the glider gains speed and height in a effective way. As the glider slows down, this wing structure gives the glider the gliding ability. The aileron structure of the glider allows the direction, trajectory, and distance of the flight of the glider to be ajusted by users. As a result, the glider system is not only a toy but also an educational tool for the user to gain some elementary understanding of aerodynamics of flights. The holding, guiding, and accelerating mechanisms of the platform allow the glider to be launched in a more stable situation.
