Abstract: Telephone headsets used by operators and airline pilot headsets are subject to substantial amounts of interfering ambient noise which detract from the intelligibility of incoming speech. Noise reduction circuitry does not altogether eliminate the interfering sound. A headset speaker (55) and error microphone (41) housing (10) are disclosed which enable a greater amount of unwanted noise elimination. The speaker and microphone (41) are configured closely with respect to each other and also to the user's ear. They are acoustically isolated in their own chamber. The microphone is located approximately on the speaker axis and protrudes substantially into the user's ear; and also is disposed close to the speaker cone surface. Additional acoustical tuning features include venting ports (13) in the housing, and acoustic damping padding at the microphone entrance and on either side of the speaker (55). These expedients enhance the ability of the noise-cancelling circuitry to effectively reduce the undesired noise heard by the user.

Abstract: The temperature of a heat reservoir (1) is varied according to a linear function which is AC modulated. At this time, the temperature difference between two points (9, 11) located in a heat flow path going from the heat reservoir to an unknown sample (8) is measured. Also, the temperature difference between two points (10, 12) located in a heat flow path going from the heat reservoir to a reference sample (7) is measured. These two pairs of points are arranged symmetrically. Then, the resulting signals are demodulated, and each signal is divided into an AC component and a low-frequency component. Using these signals, the DSC signal is separated into a heat capacity component and a latent heat component.

Abstract: A plurality of image signals are obtained, which represent a radiation image of a single object or radiation images of the single object, and which have different frequency characteristics, each of the image signals being made up of a series of image signal components. The image signal components of the plurality of the image signals, which image signal components represent corresponding picture elements, are weighted with predetermined weight factors. The weighted image signal components of the plurality of the image signals, which image signal components represent corresponding picture elements, are added to one another, and an addition signal is thereby obtained. The value of the weight factor with respect to the frequency components, which have a low signal-to-noise ratio, is rendered smaller than the value of the weight factor with respect to the frequency components, which have a high signal-to-noise ratio, in accordance with the frequency characteristics of each of the image signals.

Abstract: According to the invention, on the basis of a deviation between an optical axis direction of a projection light and a normal line direction of a projection plane, image data can be changed and displayed so as to set off a distortion of a display image which occurs due to such a deviation. A quality of the display image is raised and a use efficiency is improved. In the invention, the image data is constructed by (m × n) pixels, the left upper position is set to an origin, an X axis is set to the lateral direction, and a Y axis is set to the vertical direction. A quadrangle ABCD corresponds to mapping data of an image stored in a memory. For example, in the case where the projection plane is inclined and the display image on the projection plane is enlarged as it approaches the right, the image is changed like a quadrangle ABEF. Namely, the image data is changed while increasing a reduction ratio in the vertical direction toward the right of the image. By projecting such changed image data onto the projection plane, the distortion occurring by the projection and the distortion on the mapping data are set off, so that an image without a distortion is displayed.

Abstract: The invention provides for resource allocation logic for a computer system including a plurality of processors (17, 21) which share access to, and control of, a plurality of resources, such as disk drive units (31-35, 41-45) or busses (51-55). Resource allocation logic (300) coordinates the execution of requests received from the processors to avoid resource sharing inefficiencies and deadlock situations. The allocation logic (300) maintains a "request" queue for each processor (17, 21), seeking to satisfy all requests quickly and fairly. The queues contain an entry corresponding to each request received from its corresponding processor and an identification of resources that are required by the entry's corresponding request. The allocation logic (300) also maintains a "resources available" status array of resources which are not currently in use by any processors, or are not reserved for future use by any processors. The logic repeatedly compares each entry in the request queues with the entries in the resources available status array to detect an entry in the request queue identifying resources all of which are contained in the resources available status array. Once the allocation logic (300) can satisfy a particular request, it signals a grant to the requesting processor for the resources requested and the requested resources are removed from the resources available status array. Upon conclusion of execution of the granted request, the resources are again released to the resource allocation logic (300) for utilization by other resource requests.

Abstract: A time-domain reflectometry device and method are provided wherein TDR may be performed on active Ethernet systems. A crossover network provides proper impedance termination both for pulse information generated by the TDR and for DC path signals. If a potential collision is detected when generating TDR pulses, a collision is forced by asserting a DC bias on the network thereby simulating a collision and generating a timeout at a much lower protocol level for reducing noticeable delay to network users and increasing network throughput.
