Abstract: A control for a toaster for varying the toasting cycle includes a switch for connecting the toaster heater to a source of electrical power.  A temperature responsive resistance element senses the temperature within the cavity.          A capacitor is responsive to the magnitude of the voltage of the electrical power.  The capacitor and the temperature responsive resistance element are included within a timing circuit such that a selected duration of time for a toasting cycle to obtain a desired toast color is varied if the voltage of the power supply increases above a predetermined magnitude during the toasting cycle.         The duration of time for the toasting cycle is also varied as the temperature in the cavity increases as a consequence of operation of the toaster for consecutive toast cycles.

Abstract: In a multi-processor parallel processing computer environment different  communication  modes  are  available  for  performing  an information  distribution  operation  (e.g.,   a  broadcast)  between processors.  The technique comprises automatically selecting an optimal communications mode at operation run-time.   The selection decision utilizes hardware parameters of the system (e.g., communication speed between processors) and run-time parameters (e.g., number of nodes to broadcast a message to).   The communication mode selection decision seeks to optimize factors such as time required to execute or work space requirements of the distribution operation.

Title: Efficient digital quadrature demodulator
Inventor: INKOL ROBERT J
IPC: H03D3/00
Filed: 1995-05-29
Granted: 2002-11-19
Abstract: A digital quadrature demodulator for an intermediate frequency (IF) input signal with an analog-to-digital (A/D) converter having a sampling frequency fs and an input to which the IF input signal is applied where the IF input signal has a bandwith B<fs/4 centered about a frequency of fs/4.  The demodulator includes an arrangement to direct even numbered output signals from the A/D converter to an inphase channel and odd numbered output signals from the A/D converter to a quadrature channel where each channel contains a highpass filter and the demodulator includes circuits to decimate by 4 signals of the channels to generate, together with the filters, a quadrature output signal Q(nT) at an output of the quadrature channel and an inphase output signal I(nT) at an output of the inphase channel.  The quadrature highpass filter in the quadrature channel has an optimized transform architecture in which the filter coefficients hk correspond to those of a lowpass prototype filter with N=2k+1 coefficients after multiplication by sin(k.pi./2) where k identifies a particular stage of the filter.  The inphase highpass filter in the inphase channel has an optimized transform architecture in which the filter coefficients hk correspond to those of a lowpass prototype filter after multiplication by cos(k.pi./2).  Employing optimized filter architectures and simplified filter coefficients obtained with a new design procedure provides a practical quadrature demodulator design which can be economically implemented in hardware.

Abstract: A weedless system has been developed for personal watercraft which obtain their power by using jet propelled water pumps.  The unique weedless system has a number of elements which help to reduce weed congestion in the jet pump.          Firstly, a plurality of downwardly directed grates, which terminate at the head of the ride shoe, are used such that weeds striking such grates will tend to slide off the grates rather than become embroiled around them.  In addition, between the venturi and the steering nozzle there is located a butterfly valve which can be manually closed or opened by the operator.  Closure of the butterfly valve creates a rotating movement of the water within the jet pump to provoke shaking, cutting and dislodging of weeds that go through the great barrier.  The weeds then pass out through the water inlet back through a weed outlet passage or become pulverized such that they will pass safely past the jet pump when the valve is reopened and the boat regains normal efficiency.

Abstract: Shaped articles made of brittle material having a low coefficient of thermal expansion, for example designed as glass or glass-ceramic plates, are typically encapsulated with a holding frame made of plastic, which is produced by directly encapsulating the edges of the shaped article with plastic by injection moulding.  In order to avoid stress concentrations in the shaped article, which inevitably form as a consequence of the differences in thermal expansion and the material-dependent shrinkage behaviour, according to the invention shrinkage-absorbing elements are embedded between the holding frame and the shaped article, which elements additionally ensure a permanently elastic bearing of the shaped articles when used in practice and provide sufficient sealing during use.
