  • Patent number: 11155327
    Abstract: A trolling motor has a steering motor transmitting torque to a steering shaft, which is coupled to a lower propulsion unit such that rotation of the steering shaft rotates the propulsion unit about a steering axis. A controller is in signal communication with the steering motor. A foot pedal in signal communication with the controller has a foot pad pivotable about a pivot axis and sends electrical steering signals to the controller (and thus steering motor) in response to pivoting of the foot pad. A variable resistance device is coupled to the foot pedal and controllable to vary resistance to pivoting of the foot pad about the pivot axis based on a position, velocity, acceleration, and/or jerk of the steering shaft. Additionally or alternatively, the variable resistance device provides haptic feedback to a user via the foot pad to inform the user about information related to the trolling motor system.

  • Publication number: 20210321076
    Abstract: An optical observation instrument according to the invention, in particular a surgical microscope or exoscope, comprises an optics unit with an objective arrangement and at least one electronic image recorder, wherein the optics unit has a first stereo channel with a first beam path and a second stereo channel with a second beam path for recording a stereo image of an object field with the at least one electronic image recorder and wherein the first and the second beam path extend through the objective arrangement. Further, the observation instrument comprises a retaining apparatus which comprises a retaining bracket, which engages over the optics unit, wherein the retaining bracket comprises an operating device with a number of operating elements for controlling a retaining arm, to which the retaining apparatus is connectable.

  • Publication number: 20210312075
    Abstract: An electronic device comprises one or more sensors capturing media content while the electronic device is situated at a media content capture location. A user interface receives user input requesting transmission of the media content to another electronic device situated at another electronic device location. One or more processors determine whether the media content capture location and the another electronic device location are substantially different locations, and at least temporarily preclude, in response to the user input, the transmission of the media content to the other electronic device when the media content capture location and the another electronic device location are substantially different locations.

  • Publication number: 20210173909
    Abstract: A companion electronic device includes a communication interface, one or more processors operable with the communication interface, and an authentication device operable with the one or more processors. The one or more processors can be actuated by power received from the communication interface upon the communication interface establishing electronic communication with another electronic device. The one or more processors can delivering signals to the communication interface enabling one or more functions of the other electronic device upon confirming authentication data received by the authentication device after the one or more processors are actuated belongs to an authorized user of the companion electronic device.

  • Patent number: 5833869
    Abstract: A method (202) for etching photolithographically produced quartz crystal blanks for singulation. In a first step (202), a quartz wafer is plated on both sides with metal and subsequently coated on both sides with photoresist. In a second step (204), the photoresist is patterned and developed and the metal layer on one side is etched through to form a narrow channel in the quartz defining a perimeter of a quartz blank. In a third step (206), the quartz channel is preferentially etched partially into the wafer along parallel atomic planes to provide a mechanically weak junction between the quartz wafer and the blanks to be singulated. In a fourth step (208), the photoresist layers are stripped from the quartz wafer. In a final step (210), the quartz blank is cleaved substantially along the bottom of the quartz channel to singulate the crystal blanks from the quartz wafer.

  • Patent number: 5740064
    Abstract: A new sampling technique for waveform measuring instruments (including methods and circuits for implementing same) comprises the step of processing a series of digital signal samples through a decimator to extract a decimated sample value from each decimated sample interval in a series of decimated sample intervals. The series of digital signal samples is simultaneously processed through a digital peak detector to extract maximum and minimum values (peak detect sample values) from each decimated sample interval. For a given decimated sample interval, a difference between the maximum and minimum sample values for the interval is calculated. If the difference exceeds a glitch detect threshold value, the maximum and minimum sample values for the given decimated sample interval are transferred to a video sample memory. If not, the decimated sample value for the given decimated sample interval is transferred to the video sample memory.

  • Patent number: 5496846
    Abstract: The present invention is a method of treatment for a patient with cancer. In particular, it is a method of treating patients having breast cancer using the microtubule agent, Taxol. The present method of administration, serves to prevent or retard the adverse side effects associated with Taxol and reduces the chances of a patient developing mdr Taxol resistance. The novel method of treatment provides a low-dose, longterm exposure to Taxol in a patient.

  • Patent number: 5233546
    Abstract: A filtering apparatus permits alias-free frequency domain measurement in any of a plurality of measurement bandwidths. The input signal is first passed through one of a plurality of low-pass filters. The appropriate filter is selected by a controller to provide a cut-off frequency at least as great as the selected measurement bandwidth. An analog-to-digital convertor ("ADC") samples the filtered input signal at a sample rate (f.sub.s) set by the controller to be at least twice the measurement bandwidth. The digitized samples are then processed by a digital low-pass filter (i.e. a finite impulse response filter) to further reduce the bandwidth of the input signal to the measurement bandwidth. Operation of the digital filter is controlled by a number of filter coefficients provided by the controller as a function of the desired measurement bandwidth. A memory is provided between the ADC and the digital filter.

  • Patent number: 5043738
    Abstract: A microstrip patch antenna assembly (20, 52, 106) is formed of a patch radiator (24, 58) and a feed structure (26, 64) of microstrip feed elements (48, 50, 66, 68) disposed on opposite sides of a ground-plane element (22, 54) and spaced apart therefrom by layers (28, 30, 72, 74) of dielectric material. A single slot (108) or a pair of orthogonally positioned slots (44, 46, 82, 84) within the ground-plane element couples linearly or circularly polarized microwave power from the feed structure to the patch radiator. Additional radiators (60, 62) may be stacked above the foregoing radiator, the radiators being separated by further layers (76, 78) of dielectric material. A plurality of square-shaped raidators (58, 60, 62) may be employed for multiple-frequency operation in which case the radiator size and the thickness of dielectric material between the radiator and the ground-plane element establish a resonant frequency.
