Title: Electronic camera and device for panoramic imaging and object searching
Inventor: KOJIMA KIYONOBU
IPC: G02B27/22
Filed: 1991-06-19
Abstract: An electronic camera has sensors for detecting an image of an object, the three dimensional position and azimuth of the camera, the focusing amount and the zoom amount. The image is recorded on a recording medium together with information concerning the three dimensional position and azimuth, the focusing amount and the zoom amount. An image reproducing device for the camera reproduces the recorded image on the basis of the information so that an interrelationship between a plurality of the recorded images is clearly reproduced. Accordingly, the camera and the reproducing device are suitable for combining the recorded images so as to prepare a panoramic image, or to locate a desired article within an image of several different articles.

Patent CA-2071184-A1 (CA)
Inventor: KAZAITIS MICHAEL P
IPC: A22C13/02
Filed: 1992-06-12
Abstract: Severing a shirred stick of sausage casing from casing feed stock joined to the stick is accomplished by perforating a section of the casing across its flat width prior to moving the section through a shirring zone.  The section is then moved to a shirring zone where longitudinal movement of the casing is restrained to put the casing in tension across the line of perforations.  The resulting tension tears the casing apart along the line of perforations.  In one embodiment the shirring rolls are operable to incorporate a torn end of the casing into the shirred stick by gathering the torn end up into a pleat at the last-shirred end of the stick.

Title: Hydraulic seal assembly
Inventor: LEE JOHN
IPC: F16J15/32
Filed: 1990-02-08
Abstract: An improved seal (1) used in a hydraulic system having a piston rod (7) in a housing (5). The seal has stressing and sealing members (15, 17) with the latter being in point contact (23) with a piston rod un-der low fluid pressure and an additional point contact (29) with the piston rod under high fluid pressure. A shallow concavity (27) be-tween point contact (23) and the contact area entraps lubricating fluid when the seal is subjected to high fluid pressure. In another modifica-tion, the sealing member (17) has an incline (35) on the face in contact with stressing member (15). Thus, under high fluid pressure, stressing member (15) is forced up the incline (35), exerts increased pressure through the sealing member against the contact area and produces a high fluid pressure seal. In another embodiment, the sealing member (17) has a concave surface (25) to receive stressing member (15) such that it is centered, during low pressure operation, over a sealing con-tact area of the sealing member (17).

Inventor: ENG STEPHEN K-Y
IPC: H04L69/40
Filed: 1992-11-24
Abstract: Protection switching of digital signal transmitting and receiving hardware is realized in a "hitless" manner. The hitless switch is obtained by employing hardware switching units which can individually determine the instant to switch from an active state to a standby state and vice versa. A switch is initialized by supplying a switch request signal from a control unit to a hardware switching unit in the active state. The active hardware switching unit, upon detecting a prescribed bit condition, for example, a predetermined bit state, of the digital signal being supplied as an output therefrom, supplies a predetermined synchronization pulse to the standby hardware switching unit. In response to the synchronization pulse, the standby hardware switching unit forces the bit condition of a bit of the digital signal to be supplied as an output therefrom resulting from a current input bit to be in the same bit condition as that detected in the active hardware unit. Output circuits in both the active hardware switching unit and standby hardware switching unit are simultaneously turned OFF and ON, respectively, in the individual units by observing the digital signal being supplied as an input to both units. Upon detection of a predetermined bit condition of the input digital signal individually by each of the hardware switching units, the active unit output circuit is turned OFF and the standby unit output circuit is turned ON at the same instant. The instant of turning OFF and On of the output circuits is determined individually in each hardware switching unit. (FIG. 5)

Abstract: Abstract An infrared telephone having a first station and a second station is described. The first station is especially a telephone handset, while the second station is especially a fixedly installed remote station, for example table/wall station (base unit). According to one embodiment the first station and the second station have a single frequency oscillator, respectively, the frequency of which modulated by the electrical signals which have to be transmitted controls not only the power of the associated infrared emitter but is also fed to an associated mixing stage. The signal supplied by the associated infrared receiver is mixed with the modulated frequency of the associated frequency oscillator in the mixing stage, and the sum frequency of the received frequency and the modulated oscillator frequency generated by the mixing step is demodulated by means of a frequency demodulator, wherein the function of receipt is obtained from the resulting signal. According to a further embodiment each station works with two frequency oscillators. Furthermore, the construction of the telephone handset and of the base unit are described.
