Title: Protection from overheating of a switching transistor that delivers current to a daytime running light on a vehicle
Inventor: VILKINOFSKY JOHN W
IPC: H03K17/0814
Filed: 1999-09-22
Abstract: A protection circuit protects from overheating a switching transistor that delivers current from a power source to a daytime running light on a vehicle. The protection circuit of the present invention open-circuits the switching transistor from the power source when the temperature at the switching transistor is sensed to be above a predetermined temperature. In this manner, excessive current is prevented from flowing through the switching transistor. In contrast, prior art protection circuits control only the gate of a MOSFET or base of a BJT switching transistor. In that case, if damage to the transistor results in an effective resistance , constant flow of current through such an effective resistance results in excessive overheating or even a fire. The protection circuit of the present invention open-circuits the conductive path from the power source through the effective resistance such that current does not flow through the effective resistance. Furthermore, a latching circuit in the protection circuit of the present invention maintains the switching transistor to be open-circuited from the power source once the temperature at the switching transistor reaches the predetermined temperature. Thus, the traffic hazard or degradation of the switching transistor, which may result from the daytime running light flashing on and off, are also avoided with the protection circuit of the present invention.

Title: Headland stop for agricultural planter
Inventor: FRIGGSTAD TERRANCE A
IPC: A01B69/02
Filed: 1999-11-10
Abstract: An agricultural planter is provided with hydraulically operated devices to effect the folding and unfolding of the planter support structure between operative and transport configurations. The planter includes a laterally extending tool bar that is pivoted about a transverse axis to forwardly roll the tool bar between a lowered field operating position and a raised transport position. The transverse pivot axis is located such that the first component of the pivotal movement of the tool bar from the field operating position is generally vertical, while a second component of the pivotal movement of the tool bar approaching the transport position is generally horizontal and forwardly of the first component. The headland position corresponds to a position in which the tool bar is raised sufficiently to move the planting units mounted thereon out of the ground to facilitate the turning of the implement at the end of the field. A sensor senses the positioning of the tool bar at the headland position and activates a valve in the hydraulic circuit to stop the operation of the tool bar actuators pivotally rotating the tool bar. A bypass, in the form of a solenoid that when selectively energized will override the signal of the sensor, selectively permits the tool bar to be raised the entire way to the transport position.

Abstract: La présente invention concerne un dispositif servant à réguler un débit de fluide à l'intérieur d'un corps hôte. Ce régulateur est constitué d'une première et d'une seconde coque dont la réunion forme une structure cylindrique propre à toucher et entourer un canal sélectionné à l'intérieur du corps hôte. Les deux extrémités de cette structure cylindrique sont ouvertes. La structure présente un diamètre intérieur d'une dimension calculée pour venir s'adapter sur le canal anatomique hôte considéré, notamment l'urètre. Un piston peut être actionné par un électroaimant, ou par un dispositif pneumatique ou hydraulique, de façon à passer d'une position où l'écoulement est possible en une position de constriction où l'écoulement du fluide dans le canal devient sensiblement impossible ou restreint. Cet appareil convient à la lutte contre l'incontinence ou à la restriction de débit dans d'autres canaux anatomiques. Une télécommande extracorporelle en liaison radio avec l'appareil implanté permet à l'utilisateur hôte d'actionner l'appareil en émettant un signal commandant à l'électroaimant de rappeler le piston en état de constriction. Un autre signal provoque le retrait du piston en position d'écoulement une fois que l'utilisateur ne ressent plus le besoin d'uriner.
