摘要： A method and apparatus are provided for reducing distortion in a dynamically delayed digital sample stream of an imaging system. The method includes the steps of delta-sigma modulating an input analog signal of the imaging system at a frequency above the Nyquist frequency of the input analog signal to generate a digital sample stream and changing a length of the sample stream to delay a portion of the sample stream while maintaining synchronism between a delta-sigma modulator and a demodulator of the system.

摘要： The invention utilizes a virtual reality display to present a random noise stimulus to a patient. Using an input device a patient indicates the location of disturbances in the random noise display. In a preferred embodiment, a scanning retinal laser projects the random noise stimulus directly onto a patient's eye(s). The image is preferably presented at virtual infinity and can be imaged over the peripheral retina. A patient is directed to centrally fixate on the random noise display. A visual aid, such as a cross hair, may be included in the generated display to facilitate this focus. With a scanning laser virtual reality device having a narrow exit, the failure of a patient to centrally fixate causes the image presented to be distorted, incomplete or disappear from view. While a patient views the random noise display, the patient is directed to indicate any areas of disturbance using an input device. A preferred input device is a computer pen and tablet. This is easy to use while also viewing the random noise display. Preferably, the display changes when a patient uses the pen and tablet such that the patient sees the location being indicated either in place of or superimposed upon the random noise display.

摘要： Imaging elements, such as photographic, electrostatographic and thermal imaging elements, are comprised of a support, an image-forming layer and an electrically-conductive layer produced by coating a layer comprised of a metallo-organic compound and a film-forming binder and subjecting such layer to glow discharge treatment to render it electrically conductive. Use of a metallo-organic compound in combination with a glow discharge treatment provides a controlled degree of electrical conductivity and beneficial chemical, physical and optical properties which adapt the electrically-conductive layer for such purposes as providing protection against static or serving as an electrode which takes part in an image-forming process.

摘要： An optical transmitter and receiver for use in a fiber optic LAN and characterized by reduced pulse-width distortion, low noise, simplicity of design, and advantageous use of widely-available low-cost components. Pulse-width distortion of an optical transmitter is reduced using a pulse input and conditioning circuit that maintains the optical source in an ON state when the injected pulse energy subsides for a time closely approximating the source's turn-on delay. A pre-amplifier portion of an optical receiver is of the transimpedance type, having a low-noise first stage and a moderate-gain second stage connected to the first stage by a feedback resistance on the order of a few kilo-ohms. The low impedance of the feedback resistor minimizes thermal noise, whereas the moderate gain of the second stage still allows a high transimpedance to be achieved. A simple, single-transistor LO-LITE circuit is also disclosed.

摘要： A knee prosthesis comprises (i) a femoral component having a medial condyle and a lateral condyle and (ii) a tibial component. The rolling surface of the medial condyle is part-spherical and the tibial component has a complementary part-spherical depression in its upper surface to receive the medial condyle. The bearing surface of the lateral condyle includes a posterior part which has a curvature in a substantially sagittal plane about a first point on a transverse axis that passes through the center of curvature of the rolling surface of the medial condyle and an anterior part which has a curvature in the same plane about a point that lies on a second transverse axis parallel to, and anterior to, the first transverse axis. The tibial component has an arcuate groove to receive the lateral condyle and to permit, in flexion of the knee after implantation, limited anterior/posterior movement of the lateral side of the tibia relative to the femur. In flexion of the knee the posterior part of the rolling surface of the lateral condyle is received in this arcuate groove but, as the knee straightens and approaches its straightened condition, the anterior part of this rolling surface bears on the anterior end of the groove and thereby forces the lateral side of the tibial component to move anteriorly relative to the lateral condyle by a camming action. In this way anterior/posterior movement of the lateral side of the tibia relative to the femur is hindered in the straightened condition of the knee.
