Title: Examining biological materials
IPC: A61B5/00
Filed: 1981-01-21
Abstract: A device and method for the quantitative measurement of the absorption and scatter, as a function of wavelength, of biological materials, especially human tissue, utilizing light having a wavelength in the range of 400 to about 700 nanometers, and infrared light having a wavelength in the range of 700 to about 10<6> nanometers. Basically the apparatus comprises a light source, a wavelength selection means 50, a light delivery means 52 with an entrance facet 52a next to means 50, and an exit facet next to the tissue examined and a light detector 70 next to the tissue on the opposite side. Measurement is preferably in a scanning mode to produce a shadowgraph image or using multi- spectral imaging techniques in conjunction with a digital memory or an image storage tube. The apparatus and method may also be used with computer image reconstruction like that of computerized axial tomography. Embodiments for examining human breasts are described. <IMAGE>

Patent GB-2103053-A (GB)
Title: Improvements relating to transmission of data in blocks
Inventor: SUSANS DONALD ERNEST
IPC: H04J3/12
Filed: 1981-06-02
Abstract: Each block comprises a framing word FAW having a length of m bits and data words DWA, DWS...DWR separated by further framing bits a, b, c etc. Each data word has a maximum length of m-2 bits. Furthermore the framing bits are complemented in alternate blocks so that, nowhere in the block other than the FAW is it possible to have more than m-2 consecutive bits unchanged from one block to the next. Accordingly the framing word FAW can be unambiguously detected without imposing any restrictions on the data itself and with no risk of the data mimicking the framing word and causing false framing. The framing bits a, b, c etc. can carry slowly changing data by restricting changes of any one of these bits to occasions when at least one immediately adjacent data bit is changing. This will still ensure that the maximum unchanged sequence outside FAW is only m-1 bits long. To improve the likelihood of an adjacent bit change the main data can be complemented in alternate blocks. <IMAGE>

Title: Contactless switch
Inventor: HODGES ROBERT JAMES
IPC: H03K17/97
Filed: 1983-11-18
Abstract: A coded switch uses as its transducer elements thin silicon monocrystal strips 1, each bearing a piezo-resistive strain gauge whose resistance depends on its flexure condition. Each such strip has a small permanent magnet 2 on its free end, the magnet being, for instance, plastics loaded with a samarium-cobalt magnetically hard material. The switch is controlled by a rotatable disc 4 whose edge is recorded with a magnetic pattern. Thus as the disc 4 is rotated the silicon strip flexes towards and away from the disc, thus producing variations in the resistance of the strain gauage. These variations are detected by an amplifier chip. Several such transducer arrangements can be provided on the same shaft. <IMAGE>
