Low profile hardwood flooring strip and method of manufacture
InactiveUS6148884AConsiderable quantityImprove rigidityDovetailed workMulti-purpose machinesCircular sawTongue and groove
A method of producing a hardwood flooring product, including the steps of processing a strip of raw wood into a blank having a predetermined thickness and width, and top and bottom surfaces defining parallel planes relative to each other, and splitting the blank along the width of the blank from one side to the other to form two low profile flooring strips having the same width as the blank and a thickness less than one-half the thickness of the blank. The splitting step includes the steps of providing first and second circular saw blades mounted on spaced-apart vertical axes for rotation in a single plane intermediate and parallel to the planes of the top and bottom surfaces of the blank and positioning the blank on conveying means upstream from the saw blades with the plane of rotation of the saw blades intermediate and parallel to the planes of the top and bottom surfaces of the blank for movement of the blank from an upstream position to a downstream position relative to the saw blades. The blank is moved downstream into the plane of rotation of the saw blades during rotation of the saw blades thereby horizontally splitting the blank to form first and second low-profile flooring strips. Interlocking members, such as molded, mating tongue and groove members, are molded into first and second longitudinally-extending side edges of the flooring strips for securing together the flooring strips when placed side-to-side to form a floor.

Holders for prosthetic aortic heart valves
A holder for a flexible leaflet prosthetic aortic heart valve that is less bulky than earlier holders and minimizes obstructions to vision and working space around the valve to facilitate implantation thereof. The holder may have a central hub and three outwardly extending legs that connect directly and exclusively to tips of the commissures of the aortic heart valve for better tactile feedback when parachuting and seating the valve in the annulus. The legs are sized so that they do not overlap the commissure tips and therefore afford a better view of the sewing ring adjacent the commissures. The legs may be narrow in the midsection or split into two rails to increase visibility of the valve leaflets. The hub may be vaulted axially upward relative to the outer ends of the legs to further increase visibility of the valve. A more secure engagement between the central hub and a delivery handle is also provided to ensure the holder / handle connection does not become loose during suture placement through the sewing ring and fewer handle revolutions are required to screw in and unscrew the handle from the holder.

Multiple low speed sigma-delta analog front ends for full implementation of high-speed data link protocol
InactiveUS6442195B1Reduce quantization noiseReduce shapingTelephonic communicationSignal channelsModularityIntegrated circuit
An analog front end (AFE) circuit used in a high-speed communications system is presented that includes multiple stages each including a bandpass filter, base band modulator, low pass filter and Sigma-Delta modulator. Each stage processes a fractional portion of the total frequency of a wide bandwidth analog signal. The number of such AFE stages is configurable in parallel to process the entire bandwidth of the received signal. The AFEs can be incorporated in a single integrated circuit or similar suitable manner so as to be modular, and easily replaceable / upgradeable. To achieve minimum quantization noise and reduce manufacturing costs, the Sigma-Delta modulators in each AFE are made to have identical characteristics. Because the wideband signal is broken down into smaller frequency portions, the sampling rate, and thus the complexity and cost associated with the AFEs, is reduced significantly. In a preferred embodiment, a number of such AFEs are used in an ADSL modem for processing separate but roughly equal portions of the wideband ADSL signal containing data carrying DMT sub-channels. The separated portions are re-combined in a DMT receiver logic circuit to reconstruct the original data stream.

A magnetic mount is provided for easily mounting, positioning, and orienting a camera, sensor or other directionally sensitive electronic device. In one example the magnetic mount is a camera mount. The camera mount has a camera part that has an image sensor, electronics, battery, and communication components. The housing for the camera part has a generally concave mounting surface, with a magnet positioned inside the camera housing and adjacent to the camera mounting surface. A base part has a base mounting surface that is constructed to be attracted to the magnet. In one example, the base mounting surface is dome-shaped, with a convex curvature constructed to mate with the concave curvature of the camera mounting surface. The base part is mounted to a stable support, and the camera mounting surface brought near the base counting surface. The magnetic attractive forces pull the camera part firmly to the base part, thereby securely positioning and orienting the camera. However, the camera may be readily repositioned by pushing the camera into a new position. The size and shape of the complementary mounting surfaces may be selected according to positioning requirements.

A method and system are provided for automatically portioning workpieces, such as food products, into both shape and other user-defined specification(s). Workpieces are portioned both to shape and weight, such as to a weight-specific uniform shape, by adjusting (e.g., scaling up and down or slightly modifying) a desired template shape until the desired weight is achieved depending on the varying thickness of each workpiece. For example, from a thicker workpiece, a smaller-sized piece having a predefined shape and weight is portioned, while from a thinner workpiece, a larger-sized piece having the same predefined shape and weight is portioned. The system permits a user to scan in and edit a desired (reference) shape to be used as a template in the portioning process.

In the closed position, the cover becomes part of the housing and the form factor of the device is generally unchanged. The cover can function as an antenna for wireless communication between the device and a network or access point, and it can contain circuitry for devices such as transmitter / receivers. The cover can also function as a display device, a speaker, or an alarm.
