    摘要: A decoder that receives a Manchester encoded signal including a start of frame sequence followed by coded data values followed by an end of frame sequence. The decoder also includes a detector that detects the start of frame sequence and the end of frame sequence to determine a beginning and end of the coded data values in the Manchester encoded frame. The decoder includes an integrator with hysteresis that includes an up-down counter and provides an output signal responsive to upper and lower threshold values. The output signal is applied to a discriminator that includes a counter which counts up in response to one value of the output signal of the integrator and is reset in response to the other value of the output signal of the integrator.

    摘要: A multichannel, multipoint distribution services (MMDS) dipole antenna for receiving multiple channels in the S-band frequency range of 2000 and 3000 MHz is formed from a printed circuit board which is directly connected to a coaxial cable. On the printed circuit board are etched two stacked dipoles. Each of the dipoles has a first one-half element etched on the first side of the printed circuit board and the second one-half element etched on the second side of the printed circuit board. The first and second dipoles are oriented to be in phase with each other and are separated from each other at a wavelength spacing between 0.25 lambda and 0.40 lambda. The antenna of the present invention further uses a phase combining circuit and an impedance matching circuit etched on the printed circuit board for combining in phase the polarized signals, for canceling the non-polarized signals at 0.degree. and 180.degree., from the two stacked dipoles and for matching the impedance from the two dipoles to the impedance of the coaxial cable.

    摘要: A profound improvement in the properties and capabilities of elastomeric polyurethane joint sealing compositions is achieved by incorporating a fibrillated polyolefin of high surface area which is rendered compatible by combining it with effective stabilizing cofillers, such as titanium dioxide, calcium carbonate, carbon black, fibrous talc, serpentine, kaolin, or various other metal silicate fillers. Such cofillers are capable of improving compatibility and stabilizing the sealant mixture so that unacceptable sweat out or exudation of liquid is prevented and so that the outer surface of the applied sealant has an acceptable surface quality after curing.When 2 to 8 percent by weight of fibrillated polyolefin of macrofibrillar structure, preferably containing macrofibrils with diameters from 1 to 10 microns, is incorporated in a polyurethane joint sealant together with 8 to 30 percent of stabilizing cofillers, it becomes possible to provide revolutionary new joint sealants with remarkable properties, such as Boeing sag values of 0.1 and below for caulking compositions applied to extremely wide joints. These unique non-sag joint sealants can be compounded to form strong soft low-modulus elastomers ideally suited for vertical joints subject to extreme cyclical movement as is common in modern building construction.

    摘要: A surgical access device is configured to provide an access path via an elongated cannula so that a medical scope can be advanced into a surgical field within a patient. A housing of the surgical access device encloses a wipe assembly configured to clean a lens of the medical scope. An access passage having an axis can be defined within the housing, and the wipe assembly can be spaced from the access passage so that the medical scope is angled off of the access passage axis in order for the lens to engage the wipe assembly. Portions of the housing can define fulcrum surfaces about which the medical scope can be rotated in order to align the lens with the wipe assembly.

    摘要: A method of tuning a trap circuit to a desired frequency is provided. A constant amplitude signal is applied to the trap circuit in a progression of successively different frequency increments. The frequency increments cover a frequency range including the desired frequency. The amplitude of the signal, as modified by the trap circuit is detected and stored at each of the different frequency increments. Successive ones of the stored amplitude values are compared until an amplitude difference is found which is greater than a predetermined minimum difference and is of a polarity indicative of an increase in amplitude with the progression, and is a successor of an amplitude difference which is greater than the predetermined minimum difference and of a polarity indicative of a decrease in amplitude with the progression. The frequency at which the inflection point occurs, as indicated by the two-named amplitude differences, represents the null frequency of the trap circuit. The trap circuit is then tuned to align the null frequency with the desired tuning frequency.
