Abstract: The electronic stethoscope is designed to minimize the influence of the various types of noise while optimizing auscultation of the sounds of interest, and to enable a cardiologist to auscultate mechanical heart valves. It comprises a probe for sensing sounds of interest produced within a patient's body and for converting these sounds to an electric signal, and an audio amplifier and earphones for reproducing the sounds of interest in response to this electric signal. The stethoscope comprises: (a) a first filter unit having a frequency response that optimizes filtering of the tremor and passing of the low frequency sound components of interest in the range including the frequencies lower than 75 Hz; (b) a second filter unit having a frequency response that optimizes both attenuation of the ambient noise and passing of the sound components of interest in the range 110-1300 Hz, taking into consideration the variation of sensitivity of the human ear in function of frequency; (c) a third filter unit for passing the sounds of mechanical heart valves; and (d) a level detector detecting the amplitude level of the electric signal to activate a pulse generator of which the pulses are applied to the audio amplifier for momentarily and repeatedly disabling this audio amplifier when the detected amplitude level is higher than a predetermined amplitude level threshold.

Granted: 2001-04-10
Abstract: A mattress and pillowtop assembly includes a reversible, invertible mattress which may have a generally horizontal top and with generally vertical sides extending between the top and bottom to define a central space containing supporting and cushioning components. The mattress also includes a number of spaced, generally vertically extending straps, the opposite ends of which are connected to the exterior of the sides of the mattress adjacent the top and bottom.      The straps are used in lifting, turning and inverting the mattress to extend its utility. A pillowtop extends over the top of the mattress, releasably held in place by two sets of connectors. The first set comprises a number of spaced connectors anchored to the periphery of the pillowtop and extending outwardly therefrom. The second set comprises an equal number of spaced rings slidably mounted on the lifting straps for easy movement between the mattress top and bottom. The rings preferably bear T-shaped fittings while the first set of connectors preferably bear generally U-shaped fittings releasably engageable with the T-shaped fittings. When the mattress is to be inverted, the first and second sets of connectors are disengaged from each other, the pillowtop is removed and the mattress is then inverted, after which the pillowtop is reconnected through the connector sets to the surface of the mattress which is now the top.

Title: System for storage and communication of information
Inventor: PALMER JOHN P
IPC: G06K7/00
Filed: 1995-04-04
Granted: 1998-06-30
Abstract: A system and method for storage and communication of information between at least one first information containing terminal and a second terminal. The system and method includes generating a random number within the first terminal in response to receipt of a begin signal from the second terminal, and comparing the random number to a count incremented and maintained by a digital counter within the first terminal. When the random number is equal to the count, the first terminal transmits a request to transmit signal to the second terminal. If the second terminal responds with a first acknowledgment, the first terminal then sends an information containing signal to the second terminal. If the information containing signal is correctly received, the second terminal responds by transmitting a second acknowledgment which is received by the first terminal.

Abstract: A transimpedance circuit (201), and method therefor, frequency compensates an operational amplifier. The transimpedance circuit (201) has an input terminal (205) coupled to receive an amplified signal (205) and an output terminal (206) operative to produce a buffered amplified signal. The input terminal (205) of the transimpedance circuit (201) presents a resistive input impedance to the amplified signal at a frequency substantially near an open loop unity gain frequency of the operational amplifier (200). The amplified signal is buffered from a complex impedance of an input terminal (206) of an output driver (103). The present invention advantageously provides wide bandwidth and stable operation with loads having low complex impedance.

Abstract: A multi-channel wireway in the form of an elongated housing comprises a retaining strip and a cover removably mounted to the retaining strip.  The retaining strip includes a base of L-shaped profile and a series of vertically spaced and horizontally oriented parallel elongated shelves which define a number of compartments adapted to separately receive therein different types of electric cables and wires and other utility lines such a compressed air lines. The compartments are open-ended towards the cover and are thus  accessible when the cover is  removed.  An elongated closure plate is removable mounted to the open side of at least one compartment,  such as the compartment  containing  the power  cables,  to  deny direct access thereto even when the cover is removed. The  shelves have various  depths  to provide better access thereto. The cover is gravity-supported in a closed position thereof by the retaining strip.  The overall  configuration  of  the  wireway  eliminated openings  through  which  spilled  substances  could access  the  inside  of  the wireway with  a view of facilitating  cleaning  operations.  The  cables  can enter  and  exit  the  wireway  trough  connections provided in the retaining strip and an inverted U-shaped cover is provided exteriorly of the retaining strip  to  protect  these  connections  from  spilled substances.

Granted: 2008-04-01
Abstract: Apparatus and method are provided for segmenting (28), persing (30), interpreting and formatting (38) the content of instructions such as air traffic control instructions. Output from a speech recognizer (14, 22) is so processed to produce such instructions in a structured format such as for input to other software. There are two main components: an instruction segmenter (28) and a robust parser (18, 30). In the instruction segmenter (28), the recognized text produced by the speech recognizer (14, 22) is segmented into independent instructions and each instruction is processed. The instruction segmenter (28) receives a recognized air traffic control or other instruction, and segments it into individual commands. Utterances or other language are thereby broken up into their component instructions by detecting probable instruction boundaries. If normal processing fails, then robust backup processing (34) is invoked, as a fallback after a fixed time per word has elapsed or a processing failure has occurred. The robust parser (18, 30) allows the system (10, 20) to extract information from utterances that are not necessarily well formed or may have extraneous comments in them.

Granted: 2003-04-22
Abstract: A torso and lumbar support and position stabilizing pillow for a lateral recumbency position comprising a substantially planar base member, a main body and a lumbar support member, the main body having a top surface, a bottom surface, an outside surface and an inside surface. The main body is shaped such that the bottom surface is planar and attached to the base member, while the outside surface of the main body is also planar and perpendicular to the base member, with the inside surface of the main body being opposite the outside surface and disposed at an acute angle with respect to the base member. Optionally, the inside surface can be concave to accommodate the natural curve of the spine, allowing room for the protrusion of a person's shoulder and buttocks areas. In use, the pillow is placed in firm contact with a person's back and side to provide lumbar support when a person is lying in lateral recumbency, on their side. In addition to reducing muscle strain, the support pillow also reduces the amount of muscle tension and effort that must be put forth to maintain this position. This results in reduced fatigue.
