The removable water dispenser also has a dispenser removably attached to a home appliance and having a housing, a cover coupled with the housing, a dispensing outlet, and a filter connected to the first outlet, the second inlet, and the dispensing outlet, and the dispenser dispenses filtered water to a user.

Abstract: A water treatment apparatus that includes: at least one module which operatively and selectively treats one or both of an original household hot water received from the household hot water line and water flowing through the module and treats cold water received from an original household cold water line that flows through; a process control unit whereby a user selects a desired treatment option for the water flowing through the apparatus to be dispensed to the user; one or more plumbing connections which operatively divert the original household hot and cold water flow to the user selected water treatment module so as to dispense to the user the selected treated water; and one or more valves which operatively cooperate with the process control unit to direct the water flow within the apparatus so as to provide the user with the selected treated water.

Abstract: A filtration system for an appliance includes a water source coupled with the appliance to provide an intake water flow. A filter unit is coupled with water source to receive the intake water flow and dispense a filtered water flow. An isolation valve is coupled between the water source and the filter unit and movable between a first position and a second position. A distribution valve is coupled with an ice maker and a water dispenser of the appliance. The distribution valve receives the filtered water flow when the isolation valve is in the first position, and the distribution valve receives the intake water flow via a bypass line when the isolation valve is in the second position. The isolation valve is configured to move to the second position upon expiration of the service life of the filter unit.

Abstract: One embodiment of the present invention is directed to a clamping device with an attached arm in which the act of opening the clamp makes the arm flexible and the act of closing the clamp makes the arm rigid. By operating in this manner, the present invention may allow a worker to position the arm (while flexible) in any number of different and easily attainable positions while also allowing the worker to secure a workpiece and immobilize the arm in a single step. In another embodiment of the present invention the arm can be made flexible independently of opening the clamp.

Abstract: A CMOS-compatible peak detection circuit includes a differential amplifier stage (10), an active peak holding circuit (12), and a passive peak holding circuit (14). The differential amplifier stage (10) produces an amplifier output signal that is responsive to the difference between an input signal being monitored and feedback from the active peak holding circuit (12). Both the active peak holding circuit (12) and the passive peak holding circuit (14) store a charge representing a voltage level that is indicative of the peak amplitude of the amplifier output signal during a time interval, the time interval occurring while a disable signal is inactive. The active peak holding circuit (12) provides the maximum value signal as feedback to the differential amplifier stage (10). The passive peak holding circuit (14) provides a max signal output corresponding to the maximum value to a voltage follower stage (16) that makes it available as an output when a readback enable signal goes active.

Abstract: A serial-parallel-serial, charged-coupled device includes an array of horizontal rows and columns of closely spaced charge storage cells. Each storage cell is formed by an electrode covering an insulation layer above a semiconductor substrate. The semiconductor substrate of each storage cell includes a channel region for conducting carriers laterally through the storage cell. The channel region of each storage cell included both in a first row of the array and in any column of the array has a tilted potential gradient providing an electric field facilitating charge carrier drift within the channel region in two lateral directions, toward a neighboring storage cell of the first row and also toward a neighboring storage cell of its column.

Abstract: A two phase shift register comprises four serial registers each having an input section, a transfer section, and a lead-in section disposed between the input section and the transfer section. The input sections provide respective sequences of charge samples, the four sequences being offset in phase relative to each other by 90.degree. within the cycle of a clock signal. At least one of the serial registers comprises a first lead-in gate pair and a second lead-in gate pair over the lead-in section, the second lead-in gate pair being between the first lead-in gate pair and the transfer section. The first lead-in gate pair and the second lead-in gate pair are each driven at the frequency of the clock signal, the drive signal applied to the second lead-in gate pair being retarded in phase relative to that applied to the first lead-in gate pair by 90.degree. within the cycle of the clock signal.

Abstract: A sandwich-like fixture of expandable foam material as a core between two registering flanking plates of relatively rigid material and means through the plates securing the expandable material and plates in assembled contact relation. One or more of the plates include stabilizing and orienting feet or tab means for securing the fixture in selected position in relation to elements forming a passageway. The fixture is sized in respect to the passageway so as to provide clearance in order to achieve ingress and egress to the passageway. Then, by actuating the expandable foam material by application of heat the expanding foam closes and seals the passageway by filling the clearance between fixture and walls of the passageway with adhesive foamed material at selected points where the fixtures are positioned.

Abstract: A charge coupled device (CCD) analog shift register in a two-channel serial-parallel-serial (SPS) structure operating in a fast-in/slow-out (FISO) mode for high speed signal acquisition and temporary storage of a plurality of samples. The two CCD arrays are clocked simultaneously, and the input analog signal is demultiplexed to the two arrays. Additional transfer electrodes are provided at the input of one of the arrays, and the other array is provided with a sampling clock which is 180.degree. out of phase with the sampling clock of the first array; two consecutive samples of the input signal are taken during each transfer clock cycle. All signal samples are clocked through the arrays simultaneously and appear at the output at the same time.

Abstract: A signal-envelope display system for a digital oscilloscope includes a memory for storing minimum and maximum signal values in adjacent storage locations, an address counter for sequentially addressing the memory, and a control circuit for selectively inverting the least significant bit of the address count signal. The values retrieved from the memory are converted to analog values and a low-pass filter connects the analog values to provide a signal envelope display.
