A method and circuit for determining whether a sensor 2 is attached to a connection point 5 of a sensor interface circuit 1 of a seed monitoring system. When it is desired to determine whether a sensor is attached to a connection point, the method applies a time varying detection signal at terminal 3 to the connection point 5 via a reactive element, such as capacitor 4. The connection point 5 is connected to a first input of a comparator 9 having its other input set at a first reference voltage which maintains the comparator in a first state in the absence of a detection signal being applied. Even when a detection signal is applied, the comparator is not driven into a second state if an operable sensor is connected to the connection point 5. When the sensor is not connected to the connection point, or is inoperable, the voltage produced by the detection signal at the first input of the comparator is high enough to trip the comparator into a second state, which may be latched. Thus, the interface output 7 following a detection signal provides an indication whether an operable sensor is connected to the seed monitoring system at the connection point 5. In a preferred embodiment, the comparator may be selectively switched to a second reference voltage. In this condition, the interface output 7 is indicative of a seed being sensed by a sensor connected to the connection point 5.

A microprocessor-based electronic control system for a powershift transmission having at least one proportional actuator, such as a solenoid-operated proportional valve, is disclosed. The controller operates a plurality of on-off solenoid valves and the solenoid-operated proportional valve to provide operator-selected gear shifts in both forward and reverse directions having controlled clutch engagements achieved by modulation of clutch engagement pressure by the proportional valve. The key parameters associated with the gradual clutch engagement are all easily varied by the controller, most under program control during operation, to provide for optimized clutch engagments for smooth gearshifts. The key parameters include: fast-fill clutch delay, initial clutch engagement pressure, rate of increase of clutch engagement pressure, and the length of the reduced pressure clutch engagement interval. The electronic controller also automatically modifies selected parameters in accordance with sensed changes in temperature, magnetic flux coupling between solenoids, and variations in the voltage supply provide to the series combination of the solenoid coil of proportional valve and its solenoid driver circuit. Preferred methods of operating the electronic controller and powershift transmission are also disclosed.

A drive system for a vehicle permitting the use of an operator's arms and legs to power the vehicle. A multispeed hub assembly is offset from a powered wheel assembly and drives same with a roller chain. Arm and leg power is imparted respectively to a hand crankshaft and a live axle which power is transmitted to the multispeed hub via additional roller chains. A speed control for shifting the multispeed hub is actuated by handgrip rotation during normal hand crank operation to permit speed changes without release of either handgrip. A brake mechanism on the hand crankshaft actuates brake cables actuating caliper brakes upon reverse rotation of the hand crankshaft. The multispeed hub may include an internal coaster brake mechanism in one form of the invention.

A drive system for an operator powered vehicle utilizing both arm and leg power. Leg power drives an axle carried sprocket coupled to a torque tube via a roller chain. A hand crank is powered by arm motion and is coupled to a concentric torque tube by a unidirectional clutch. Rotary motion is accordingly imparted to the torque tube by the arms or legs, jointly or individually, which motion is transmitted to a wheel hub via a roller chain and sprocket arrangement. A chain shifter provides a variable speed power transmission between said torque tube and the wheel hub. Brake cable actuating members on the wheel axle and the hand crank permit selective tensioning of brake cables actuating front and rear wheel brakes. A modified form of the invention dispenses with the torque tube. Driving and driven sprockets of a hand crank assembly are fixedly mounted on a hand crank.

An improved contact lens and method of forming the same which causes the lens to adopt and maintain a particular angular orientation upon the eye of a wearer. One or more characters are formed in relief upon a surface of the lens at a point which is intended as the topmost point in the lens when properly oriented. The relieved characters may be used alone or in combination with previously-known means for effecting orientation of the lens.

A system and a process for producing methane gas by anaerobic digestion of feed materials containing suitable organic materials. The system includes a plurality of digestion modules arranged primarily in series. Each digestion module is positioned with its slurry inlet port at a slightly lower elevation than the slurry outlet port of the preceding digestion module. The number of digestion modules is dependent upon the particular feed material to be digested. Each digestion module can be sampled and controlled independently. The process includes grinding and pulping the feed material, mixing the feed material with a liquid to prepare a slurry, charging the initial digestion module with slurry and transferring the digesting slurry to the next successive digestion module and subsequently to each successive digestion module after predetermined time periods until the digestion process has been completed. The liquid is separated from the digested slurry for recycle through the system. The resulting sludge is useful for a variety of purposes.
