Abstract: A power driven mechanical toothbrush (20) is disclosed. A replaceable toothbrush head member (24) has tuft blocks (40) retained generally therewithin and extending laterally outwardly from the cam shaft (42). Each tuft block (40) has at elast one tuft of bristles (52), usually four, secured within the tuft block (40) and extending upwardly therefrom. Each of the bristles (54) has a distal end at a distance from its tuft block (40), and the bristles in each tuft are generally parallel to each other. The toothbrush head member (24) is adapted to receive and retain the tuft blocks in sliding relation therein, so that each tuft block (40) slides line-arly in a direction parallel to the longitudinal tuft axis (53) as guided by guide rails (39) within the head member, between a re-tracted position and an extended position. Each tuft block is driven from its retracted position to its extended position by a rotat-able cam shaft (42).

Title: Method and apparatus for connecting a node to a wireless network using a standard protocol
Inventor: GLEESON BRYAN J
IPC: H04L29/08
Filed: 1994-10-04
Granted: 2002-04-30
Abstract: Standard protocols, such as those commonly used on LAN networks, are used to connect nodes (104, 106, 108 and 110) to an enterprise network (102) via a wide area wireless network (100). Within the appropriate protocol stacks, the standard protocols are optimized by filtering some packets, eliminating and reducing the size of data packets. The optimized data packets can be transmitted over the wireless WAN, increasing WAN efficiency. The optimization is accomplished by inserting an additional optimization layer (610) into the stack between the existing layers. The optimization layer accepts the normal protocol signals generated by the surrounding layers and generates outputs which mimic protocol layers which the surrounding layers expect. Consequently, the optimization layer operates transparently with respect to the existing protocol stack layers.

Abstract: A method for a telecommunication subscriber to obtain information associated with another telecommunication subscriber using telecommunications terminating equipment with data receipt and visual display capability, such as an analog display service interface compatible telephone, and an advanced intelligent network (AIN), accessible through a public switch telephone network (PSTN). In the method, a caller sends a first communication to the PSTN including an information retrieval service number. In response to receiving the first communication, the AIN, through the PSTN, sends a message to the caller prompting the caller to communicate a subject telephone number. The caller, in response sends a second communication including the subject telephone number. In response to receiving the second communication, the selected data is retrieved from a database and then sent by the PSTN to the caller's telecommunications terminating equipment in a response message for visual display of the data.

Title: Improved bidirectional gasket having water energizing pockets
Inventor: WESTHOFF JAMES A
IPC: F16L5/02
Filed: 1998-10-08
Granted: 2005-08-23
Abstract: A bidirectional gasket providing a water-tight seal between an opening in a manhole assembly and a pipe extending into said opening having a T-shaped anchoring portion for embedment in a manhole opening. An A-shaped pipe engagement portion is joined to the anchoring portion by a connecting web which facilitates bending of the gasket. The A-shaped portion has "legs" and recesses which form water pockets preventing water from entering into the manhole assembly between the gasket and the pipe. The durometer of the gasket enhances the water tight seal of the legs with increasing water pressure. The pipe engaging portion accommodates a greater outside pipe diameter compared with conventional connectors due to reduced volume, by providing voids within the connector. The gasket has the ability to accommodate diameter deflection or ovation in rigid and flexible pipe materials. The A-shaped profile provides greater angular deflection and/or pipe misalignment allowance compared with conventional connectors. Tapered projections near the apex thereof wipe the external periphery of a pipe upon insertion and further contribute to compression of the connector in the nose portion, while preventing the projection from flipping over during pipe insertion. The web joining the anchoring portion to the pipe engagement portion has a tapered cross section, increasing in thickness toward the pipe engagement portion enhancing compression of the web against the pipe. The connecting web and interior periphery of the T-shaped anchoring portion are provided with integral projections which eliminate profile thinning and significantly reduce water infiltration. The simplified water pocket recesses ease installation problems and prevent pull-in of the water pocket which results in a connector failure.

IPC: A61B5/296
Filed: 1997-04-07
Granted: 2004-06-29
Abstract: A method and apparatus for determination of heart rate, heart stroke volume, and cardiac output from thoracic bioimpedance signals and electrocardiograms. A unique bioimpedance electrode arrangement is employed, and the bioimpedance signals are corrected for gain phase-frequency distortion through the use of sinusoidal test signals through the measuring or detection electrodes to identify distortions and correct for same during actual measurements. Time-derivative bioimpedance signals are employed, the power spectrum calculated, and a novel autoconvolution procedure used to emphasize the heart rate harmonic. Breath waves and other signals not indicative of the patient's cardiocycles are removed. Left ventricular ejection time is derived from the bioimpedance signals, and an improved version of Kubicek's equation is employed to derive heart stroke volume and thus cardiac output.

Abstract: A holder for supporting flower arrangements has first and second compartments for receiving first and second water retaining foam blocks. When mounted on the holder, the first foam block has a top surface which is parallel to the bottom Wall of the first compartment. The second compartment has a bottom wall which intersects the bottom wall of the first compartment at an angle greater than zero, and the second foam block has a top surface which is inclined at such angle relative to the top surface of the first foam block so that the holder can be mounted on a support with surfaces intersecting at an angle and both surfaces will be covered.      Stems of flowers can be inserted orthogonally into the top surfaces of both the foam blocks to provide that flowers extend from the holder vertically and at such angle relative to the vertically extending flowers. One side surface of one foam block abuts a side surface of the other foam block and at least one of the blocks is tapered at its side to permit the abutting of the side surfaces and such orientation of the top surfaces of the blocks. A water receptacle underlies the bottoms of the compartments for holding any water which drains from the foam blocks by way of apertures in the bottom walls.

Inventor: PEREZ JOSE
IPC: F15B15/10
Filed: 1999-04-26
Granted: 2007-11-20
Abstract: The device comprises an elongated elastomer tube, sealed tightly by clamps at each end against disk shaped end pieces, the one end disk fixed and the other sliding, axially to the other disk, on restraining rods. An orifice in the fixed disk permits the injection of pneumatic pressure causing the expansion of the elastomer tube. Surrounding the elastomer tube is a restraining tube of woven fabric or other material which will not expand radially. The second tube is also affixed to each end disk by the clamps and has sufficient length to reach between the two disks when the disks are at their farthest distance from each other. When the disks are not fully distanced from each other, the outer tube crumples axially but not radially. Action commences when the disks are closest to each other. Controlled pneumatic pressure injected through the orifice causes expansion of the elastomer tube. The outer restraining tube causes all force to be directed to move the sliding disk away from the fixed disk on the guiding mechanism, thus creating an axial force.
