  • SYSTEMS AND METHODS FOR CONTROLLED ILLUMINATION OF LIGHT-EMITTING DIODES
    Publication number: 20210289600
    Abstract: Systems and methods are disclosed for controlled illumination of LEDs. An example system comprises: a plurality of LEDs; an LED controller; a current buffer adapted to receive an input bias level signal from the LED controller, wherein a set of LEDs to be controlled together are connected in parallel with each other in a circuit with the current buffer; and at least one current limiting resistor connected in the circuit with the plurality of LEDs and the current buffer. The systems and methods are adapted to control the illumination of the LEDs by applying a constant voltage to the circuit based upon the input bias level signal, thereby controlling the illumination of the light-emitting diodes without the use of pulse width modulation. Crosstalk interference with RFID components due to pulse width modulation is thereby avoided.

  • Grading a piston with deposits using measurement data and thermal scan data
    Patent number: 11119005
    Abstract: A method and system for grading pistons with deposits is disclosed. In an embodiment, a piston with upon its outer surface deposits is three dimensionally scanned and compared to a reference model to detect the location and geometry of the deposits. The location and geometry of the deposits are recorded and used to grade the pistons. The piston is increased in temperature and thermally scanned. The deposits are identified based on the temperature differences measured with respect to the temperature of the outer surface of the piston. Deposit characteristics can be generated from the identified locations of deposits and the magnitude of temperature difference with respect to the outer surface. The deposit characteristics are recorded and used to grade the pistons.

  • Method of installing a fastener into a surface and a washer for use therewith
    Patent number: 11085485
    Abstract: A method of installing a fastener into a surface without defacement of the surface utilizes an annular washer of a viscoelastic material placed about the shank of the fastener such that, upon driving the fastener into the surface via a driving tool, the fastener head clamps against the washer to cause it to viscoelastically expand radially outwardly from the fastener shank until the inner opening of the washer expands to approximately the diametric dimension of the enlarged head of the fastener, whereupon the washer can be removed from the fastener. The interposition of the washer between the driving tool and the surface protects the surface against defacement.

  • Insect water supply system
    Patent number: 11051490
    Abstract: The insect water supply system is configured to prevent the insects (such as crickets) from self-contaminating the water supplied to the insects' rearing enclosure. The system is designed so that the insects drink in an inverted (i.e. upside down) and elevated position—consequently the insects' feces fall downward toward the ground and away from their water source—and therefore do not contaminate the insects' water supply.
