    摘要： A communication system is presented whereby sequences of video screens sent from a host CPU to a video controller can be stored and subsequently retrieved by a terminal located remote from the host CPU. The host CPU and video controller form part of a server arranged within a distributed computing system. An administrator situated at the remote terminal can retrieve select video screens produced during server operations to determine information regarding the server configuration and possible causes of server failure or future failure. The sequence of video screens thereby represent video screen changes stored upon a server controller adapted for coupling to the server expansion bus. The video screen changes represent a sequence of video screen changes occurring prior to server failure or after server reset. Those changes provide beneficial information to an administrator located remote from the server, and allows the administrator to communicate with the server using several possible communication protocols. The server controller snoops display data written from the host CPU to the video controller and mirrors the display data upon buffers within the server controller. Information within the buffers can be called upon by a remotely situated administrator regardless of whether server power is lost in the interim.

    摘要： A method and system for compressing required bandwidth for signals possessing redundancy, without substantial loss of intelligence or signal-to-noise ratio. This is effected by sampling the input signal to yield an appropriate first group of samples, transforming the said group into a second group of samples displaying reduced power but yet retaining intelligence and signal-to-noise ratio, and then operating upon the transformed sample group to recover original power levels-and in the process reducing required bandwidth. A system is disclosed wherein these operations are effected by applying the input signal to a tapped delay line-the outputs from said line comprising the aforesaid first group of samples. Such outputs are each applied through weighting networks to derive the transformed, low-power, second sample group. After being passed through analog-to-digital converters, the low-power samples, then in parallel binary form, are gated and passed through a suitable delay line to effectively combine the low-power samples into higher power signals of number per unit time reduced in comparison to the original sampling rate.

    摘要： Apparatus for measuring corneal thickness. A transducer is provided that transducer includes a plurality of peizo-electric arcuate segments arranged in a circle to form an annular member. The segments are electrically and acoustically isolated from each other. Leads are connected to each segment for the transmission of electrical signals. The transducer is one component of a system for measuring corneal thickness. Also included in the system are a transmitter which is connected to the leads for applying an electrical signal to the segments to produce respective sound pulses, respective receivers connected to the leads for converting the signals into distance measurements, an averager capable of averaging the distance measurements and a display device to display the average distance.
