  • Patent number: 7104262
    Abstract: A versatile book is disclosed for hanging pneumatically actuated devices (e.g., airguns or spray guns). In the preferred embodiment, the versatile hook comprises: a hook body having a base with an annular section that defines a through-space corresponding to the shape of the pneumatic device's cylindrical extension tube or barrel; a hook-shaped extension attached to the body; and, positioning-and-mounting means for selectively positioning the hook, around and along the barrel, and thereafter mounting the body in a temporarily fixed position onto the barrel, with the hook-shaped extension facing towards or away from the discharge nozzle. Upon loosening a bolt, the preferred hook can be reoriented.

  • Patent number: 6445326
    Abstract: An analog to digital convertor includes a pulse width modulated circuit (PWM) responsive to an analog parameter of an analog signal. The PWM circuit generates a pulse having a duty cycle proportional to the analog parameter. A counter generates a plurality of counterpulses during the pulse duty cycle and a sub-cycle pulse generator generates a series of subcycle pulses during each of the counterpulses. A latch circuit latches the state of the subcycle pulse generator at a predetermined time relative to the termination of the PWM pulse and a logic circuit counts the number of counterpulses which are generated during the PWM pulse. A most significant bit number is represented by the number of counter-pulses and a least significant bit number is determined by the state of the subcycle pulses in the latch. These two numbers added together provide a digital number representative of the analog parameter.
