Abstract: A method and system for concrete monitoring calibration using truck-mounted mixer drum jump speed data selectively assimilated from previous deliveries. In preferred embodiments, the invention surprisingly employs data obtained using different concrete mix designs, as well as jump speed data obtained from high speed mixing after the trucks arrive at the construction delivery site and before pouring the concrete into place at the site. The method involves measuring energy (E) in terms of pressure or force associated with mixing the concrete (“E1”) at a first drum speed (“V1”) and measuring energy (E2) after a speed jump of +/?2.5 RPM or more to a second drum speed (V2). Slump is calculated using low speed energy/speed/slump curve data, or pre-stored equation wherein slump(S) is derived as a function of slope of the line defined by E1, V1 and E2, V2 and intercept of the plotted relationship (at E axis where V is zero).

Abstract: A system for producing a live performance combining separate performances of remote players comprises a plurality of connected computing devices transmitting a plurality of communication streams to one another in series. The system can employ the plurality of series conceded computing devices, each for receiving and playing back an immediate predecessor communication stream from an immediate predecessor computing device, and each for capturing and transmitting a current performance along with the played back immediate predecessor communication stream. Typically, the individual performances of remote players can comprise live instrument music and/or vocals which can also include live video.

Abstract: Structures with altered crystallinity beneath semiconductor devices and methods associated with forming such structures. A semiconductor layer is implanted over a first depth range of an inert gas species to modify the crystal structure of a semiconductor material of the semiconductor layer and form a first modified region. The semiconductor layer is annealed with a first annealing process to convert the semiconductor material within the first modified region to a non-single-crystal layer. The semiconductor layer is also implanted with ions of an element over a second depth range to modify the crystal structure of the semiconductor material of the semiconductor layer and form a second modified region containing a concentration of the element. The semiconductor layer is annealed with a second annealing process to convert the semiconductor material within the second modified region to an insulator layer containing the element.

Abstract: A process is disclosed for using the existing Universal Resource Identifier (URI) history feature of browsers to maintain user preference settings, or other state information, used by one or more web sites or other systems. In one embodiment, when a user makes a particular preference selection on a web site, the user's selection is recorded in the browser's URI history by causing the browser to access a URI (or a set of URIs) representing the particular selection. The same or a different web site may subsequently test the browser's URI history for this particular URI by including appropriate JavaScript or other executable code in a page requested by the browser. Depending upon the outcome of this test, the web site and/or the page's executable code may take an appropriate action or inaction consistent with the preference selection.

Abstract: A sensor apparatus incorporates a responding gas sensor to measure and display gas concentrations or other indications. Calculation of a gas concentration may be derived from an output signal of a light detector through the use of a linear equation. Through the use of digital processing an output signal may be sampled to calculate a gas concentration based on a rate of change of the output voltage.

Abstract: A phased array antenna includes a plurality of subarray lattices connected together in a linear configuration and forming a substantially rectangular aperture. Each subarray lattice is clocked progressively to obtain an aperiodic aperture and reduce grating lobes.

Abstract: A phased array antenna may include a plurality of antenna elements, at least one respective phase shifter connected to each antenna element, and at least one respective gain element connected to each antenna element. The phased array antenna may further include at least one controller for determining and controlling both phases and gains of the phase shifters and gain elements, respectively, to provide beamsteering in a first direction for a signal of interest. The controller may also iteratively determine and control phases of the phase shifters to provide a null in a second direction for a signal not of interest, and without determining or controlling gains of the gain elements.

Abstract: The invention relates to an adjustable keyboard to be used, for example, at a computer terminal. The preferred embodiment is in the form of a keyboard having a number of keys, the keyboard being formed in at least two segments which are mutually movable relative to one another using a hinge or joint. Each of the segments of the keyboard has mounted thereon some of the keys. The relatively movable nature of the keyboard aims at reducing stress and discomfort to the user by eliminating contortion to the user's wrists. More particularly, discomfort to the user caused by pronation of the wrists and/or ulnar deviation of the wrists is reduced. The hinge or joint may be in the form of a ball and socket-type joint with a locking mechanism, which preferably includes a pivoted handle, in the form of a lever, used for locking and unlocking the hinge or joint.

Abstract: Method and system to determine an initial suitable configuration of an adjustable keyboard is provided. This system may include a pronation gauge wherein the pronation gauge has a readable scale and the readable scale is adapted to indicate a specific degree of pronation for the user's hand depending upon a specific resting orientation of the user's hand within the gauge. This method may include measuring the resting pronation position of the user's first hand and then adjusting the pronation orientation of the ergonomic adjustable keyboard to a position that coincides with the measurement of the pronation position of the user's hand.

Abstract: A control instrument for a system for generating acoustic output which includes a processor for receiving user input signals and control the acoustic output in response to the user input signals. The control instrument includes an instrument body, and at least one sensor element carried by the instrument body. The sensor element generates user input signals upon tactile actuation of the sensor element by a user. The user input signals indicate the location of contact and amount of force applied to the sensor element by the user. A music synthesis system and a sound processing system each including the control instrument are also provided.

Abstract: A signal processor acts upon a stream of incoming musical performance data including note-on signals and outputs a stream of musical performance data including note-on and note-off signals. The incoming performance data is dispatched to a multiplicity of output channels depending on the time interval between successive incoming note-on data. Notes played in very rapid succession are identified as chords and are performed with identical musical parameters such as duration and instrumental timbre. Notes played in slow succession are identified as polyphonic and are performed with the same instrumental timbre. Notes played at an intermediate speed are identified as melodic and are performed with the same instrumental timbre and a variable staccato or legato effect.

The ergonomic mouse allows for the operator's hand to remain in a relaxed position in as near a state of repose as possible while operating the mouse. The shape of the mouse reduces several of the known high risk postures during mouse use.
