A collapsible steering column is used with motor vehicle. The motor vehicle has a frame. The steering column has an outer jacket and a stationery bracket. The outer jacket is releasably coupled to the frame. The stationery bracket is coupled to the frame. The outer jacket and stationery bracket are collapsible in response to release of the outer jacket from the frame. An electrically actuated brake mechanism is coupled between the stationery bracket and the outer jacket and provides an infinitely variable resistive force to the collapse of the outer jacket and the stationery bracket.

Programmable energy absorbing system

A pedal assembly is mounted on a body structure of a motor vehicle and is used to generate a control signal for vehicle system. The pedal assembly includes a support mounted to the body structure and a pedal arm with an upper end pivotally mounted to the support for movement relative to the body structure and a lower end for supporting a pedal pad. The pedal arm is movable between a plurality of operational positions as a force is applied to the pedal pad. A magnet is mounted to the pedal arm for pivotal movement with the pedal arm between the various operational positions. The magnet is preferably permanent magnet having a cylindrical shape and including multiple poles alternating between positive and negative orientations about the circumference of the magnet. A noncontact sensor is mounted adjacent to the magnet such that the sensor remains fixed relative to the pedal at all operational positions. The sensor generates an electric control signal that is used to control a vehicle system as the pedal arm is moved between the operational positions. The signal varies in magnitude by the extent of angular rotation of the magnet relative to the sensor.

Pedal assembly with non-contact pedal position sensor for generating a control signal

The invention provides a method of and an implementing assembly for shifting the transmission 12 of a vehicle having a battery 24 between park and various shift positions with a reversible motor 10 by supplying electrical energy from the battery 24 to the motor 10 to shift the transmission 12 in response to a shift selection 14 and characterized by storing electrical energy in a super capacitor 20 and transmitting that electrical energy stored in the capacitor 20 to the motor 10 for actuating the motor 10. The capacitor is placed in parallel with the battery 24 for charging the capacitor and in series with the battery 24 and the motor 10 to transmit the stored energy of the capacitor to the motor 10. The capacitor 20 stores sufficient electrical energy to actuate the motor 10 independently of the battery 24.

Capacitive supercharger for electric shift mechanism

An apparatus for transferring power and communication data across an annular gap comprises an inductively-coupled primary coil winding and secondary coil winding rotatable therein. Two signal oscillators are electrically coupled to a transistor for controlling current flow through the primary coil winding, thereby inducing a signal with a respective frequency in the secondary coil winding. An electronic switch operates so as to apply one of the two signals to the transistor for charging a capacitor coupled to the secondary coil winding, and operates so as to apply the other of the two signals to the transistor for discharging the capacitor. Actuation of control devices operate so as to modulate the impedance of the secondary coil winding. The inductive coupling of the two coil windings results in this modulation being mirrored by a modulation of the voltage developed across the primary coil winding. The primary coil winding voltage is compared to a threshold voltage for decoding the modulated voltage and determining actuation of the control devices.

Inductively coupled energy and communication apparatus

A system for indicating level of material in a vessel comprising a probe which includes a plurality of electrically discrete probe elements of electrically conductive construction position within a material vessel in a spaced array extending height-wise of the vessel. Each probe element has electrical characteristics which vary as a function of proximity of material thereto within the vessel. In one embodiment, the probe elements comprise capacitive elements responsive to varying dielectric characteristics as material approaches each element. In another embodiment, having particularly utility in fuel level sensing applications, the probe elements comprise resistance elements responsive to cooling through immersion in fuel for varying voltage drop thereacross. Electonic circuitry is coupled to the several probe elements for detecting material level as a function of electrical characteristics of the probe elements. Preferably, such level detection is accomplished in discrete steps corresponding to separation between probe elements.

Material level indicator

An electric indicating target for use in shooting practice which provides a user with a display indicating the zone of the target face that has been hit by a shot. The target includes a planar surface of electrical resistance elements formed on the target face and divided into a plurality of electrically insulated sectors. When the surface of a sector is penetrated by a relatively small projectile, the resistance of the sector increases by an amount indicative of a shot hitting the sector. The target further includes external circuits, each connected to a different sector of the target, that store the resistance of a sector and detect changes in this resistance indicative of a projectile hitting the sector. After a sector is hit, the associated circuit first signals so, and then stores the new resistance of the sector. A display device is connected to the external circuitry in order to provide a user with messages indicating which sector has been hit.

Electric target and display

A system for indicating level of material in a vessel as a function of material capacitance comprising a pair of parallel probe electrodes which extend through the vessel and have lower portions disposed beneath the vessel outlet in direct electrical contact with material whose level is to be measured. An electrical signal having both ac and dc components is fed to one of the electrodes, and detected at the other electrode, such that the detected ac signal component varies with both capacitance and conductance of material disposed between the electrodes while the dc signal component varies substantially as a function solely of material conductance. The dc signal component is used to compensate the ac signal component for variations in conductance, so that an output signal is provided which varies as a function of material level between the electrodes substantially independently of material conductance.
