Abstract: An apparatus and method for plumbing a conventional bathtub drain to a conventional shower drain. A wooden framework is used wherein a pipe is placed that has one end connected to a pre-existing bathtub drain and the other end connected to a shower stall drain. The framework requires a minimal height because the pipe is oval shaped, thus providing a large enough volume for fluid flow while limiting the height required for such a pipe.

Abstract: A computer-implemented method for restoring a wrapped audio signal comprising a plurality of digitised signal samples at respective sample times, the method comprising: estimating a sequence of corrections comprising a sequence of numerical values the estimating comprising, for each signal sample: applying, at the sample time, a numerical filter to each of a set of potential corrections to determine a filtered value associated with each set of potential integer corrections wherein the filter enhances the filtered value at sample times when a change in a degree of wrapping occurs relative to sample times when a change in degree of wrapping does not occur; determining a cumulative objective over a plurality of signal samples by accumulating objective values and determining a sequence by selecting for each sample time a correction from the set of potential corrections wherein the correction for each sample time are selected to optimise the cumulative objective.

Abstract: A closure device which a consumer or bag manufacturer may affix to most any bag comprises an elongated first strip of flexible material and a thin bendable wire and second strip of material of substantially the same length as the first strip and longitudinally aligned with and affixed to the first strip. The first strip includes an opposite adhesive surface which is covered by a protective strip of release paper at the time of manufacture. A plurality of individual closure devices may be manufactured in sheet form with perforations extending between each adjacent closure device on the sheet. When needed, the consumer tears a closure device from the sheet. The consumer peels away the release paper revealing the adhesive surface and affixes the closure device to the outer surface of a bag. In one preferred method, the consumer affixes the closure device in a traversing manner with the closure device extending between the opposite closed and open ends of the bag.

Abstract: LED lamps having a high color rendering index are disclosed. In some embodiments, such lamps also exhibit high lumen maintenance and low color drift during lamp warm-up. The lamps may include, for example, a light emitting diode (LED) kernel having a mixture of red and blue LEDs, and a converter including a red phosphor in an amount ranging from greater than 0 to about 10 weight % of a total phosphor content of the converter.

Abstract: There is herein described a lamp for providing white light comprising a plurality of light sources positioned on a substrate. Each of said light sources comprises a blue light emitting diode (LED) and a dome that substantially covers said LED. A first portion of said blue light from said LEDs is transmitted through said domes and a second portion of said blue light is converted into a red light by a first phosphor contained in said domes. A cover is disposed over all of said light sources that transmits at least a portion of said red and blue light emitted by said light sources. The cover contains a second phosphor that emits a yellow light in response to said blue light. The red, blue and yellow light combining to form the white light and the white light having a color rendering index (CRI) of at least about 80.

Abstract: A method of generating a view of a computer-generated environment using a location in a real-world environment, comprising receiving real-time data regarding the location of a device in the real-world environment; mapping the real-time data regarding the device into a virtual camera within a directly-correlating volume of space in the computer-generated environment; updating the virtual camera location using the real-time data, such that the virtual camera is assigned a location in the computer-generated environment which corresponds to the location of the device in the real-world environment; and using the virtual camera to generate a view of the computer-generated environment from the assigned location in the computer-generated environment.

Abstract: Solid state light source driving and dimming systems are provided that enable a plurality of solid state light source (e.g., LED) driver circuits to be coupled to a single AC voltage source. The driver circuits may include constant current circuitry configured to generate a constant AC current from the AC voltage source, and rectifier circuitry configured to generate a DC current to drive the solid state light source (e.g., LEDs). Dimming control includes shunt circuitry operable with a PWM switch to shunt the AC voltage source during certain portions of a PWM signal and to decouple the shunt circuitry from the AC voltage source during other portions of the PWM signal. Shunting the AC voltage source causes the interruption of the DC current to effectively turn off the LEDs. Decoupling the shunt circuitry may improve overall efficiency of power transfer to the LEDs.

Abstract: A sonar imaging system for a watercraft is disclosed. The sonar imaging system comprises a transducer coupled to the watercraft and having at least one side scanning element and at least one bottom scanning element, an electronic control head unit coupled to the transducer and configured to display sonar images. The downward acoustic elements may be circular and the side scan acoustic elements may be rectangular. A software filter may be provided to remove noise generated by a spark plug or other operation of a motor for the watercraft.

Abstract: A sampled digital audio signal is displayed on a spectrogram, in terms of frequency vs. time. An unwanted noise in the signal is visible in the spectrogram and the portion of the signal containing the unwanted noise can be selected using time and frequency constraints. An estimate for the signal within the selected portion is then interpolated on the basis of desired portions of the signal outside the time constraints defining the selected portion.

Abstract: A trimming knife is disclosed having an elongate body which is tapered from a rounded wider end to a narrower end and which has an end face. A coiled tape measure is housed within the rounded wider end of the elongate body, which has an end portion extendable from a slot formed in the end face. A flashlight is housed in the elongate body and arranged to show from the end face and illuminate the tape measure when the tape measure is extended from the slot. Finally, a blade, or a socket for mounting said blade, is provided in the end face so that a cutting edge of the blade extends alongside and at the level of the tape measure when the tape measure is extended from the slot.

Abstract: A tape measure and accessory combination comprises a housing (10), with a retractable tape measure (12) housed therein, which can be extended through a slot (13) in the housing, a blade (15) mounted adjacent the slot so that said blade can use the tape (12) as a straight edge for cutting and scoring. A flashlight bulb (16) is mounted so as to shine along the tape measure when extended, and other accessories can be provided, such as a note surface (21) or pad (120), a pencil (22) or (121), and an angle finder (115) incorporating a bubble vial (116).
