Abstract:
The EKG cord management system is a cable management system. The EKG cord management system is configured for use with the leads of an EKG machine. The EKG cord management system comprises a plurality of lead structures, a probe connector, and a housing. The EKG cord management system deploys the plurality of lead structures from the housing. The EKG cord management system retracts the plurality of lead structures into the housing. Each lead structure selected from the plurality of lead structures measures electrical activity in a human body. The probe connector electrically connects each of the plurality of lead structures to a machine known as an EKG machine.
Abstract:
When boosting a battery, a direct current boosting voltage is applied between the positive and negative terminals of the battery via a pair of cables of predetermined length. In order to supply a boosting voltage of predetermined constant value, a direct current voltage source supplies the boosting voltage to the battery not only through the pair of the cables, but also through a high current adjustable load. Of course, the direct current voltage source supplies a voltage of value higher than the boosting voltage predetermined value. A voltage controller detects the voltage between the ends of the two cables adjacent to the voltage source, and the voltage drop in the pair of cables, and varies the high current adjustable load in response to the detected voltage and voltage drop so as to adjust the boosting voltage at the predetermined constant value.
Abstract:
An adjustable electrical load bank which comprises an upper and lower horizontal, electrically conducting plates mounted parallel to each other on a frame and both electrically insulated from this frame. The lower plate is fixedly mounted on the frame while the upper plate is movably connected thereto through four spring devices. Three vertical piles of disk-shaped carbon elements are disposed between the two horizontal plates and each have an electrical resistance between their respective upper and lower ends which varies with pressure applied thereon. An upper and lower pistons separated by an helicoidal spring are disposed in a vertical cylinder mounted on the frame. The upper piston is associated with a manually operated cam while the lower piston is fixedly connected to the upper plate. Upon operation of the cam, the helicoidal spring produces a force acting against a force generated by the four spring devices for applying pressure on the piles. An accurate adjustment within a range of light pressures on the piles is therefore enabled due to these reverse forces for thereby allowing to give to the pile resistances corresponding values. When the helicoidal spring is completely compressed, the cam can still be operated to apply relatively high pressures on the piles to vary their resistances accordingly. The load bank is particularly suitable for use in wide current range battery testers.
Abstract:
A system for use in boosting the weak battery of a vehicle to permit operation of the starter of such a vehicle including at least one booster battery for providing the required energy for boosting the weak battery. The circuit for connecting the booster battery to the weak battery of the vehicle includes a relay having an electromagnetic winding connected to an energizing circuit and an armature responsive to the electromagnetic winding for operating a main set of contacts and an auxiliary set of contacts. A resistor is connected in series with the auxiliary set of contacts and the series combination of said auxiliary set of contacts and said resistor is connected in parallel with said main set of contacts. The booster battery is connected to the weak battery through said sets of main and auxiliary contacts and the armature of the relay is designed in such a way as to close said auxiliary set of contacts ahead of said main set of contacts and to open said auxiliary set of contacts after said main set of contacts so as to prevent arcing at the terminals of said main set of contacts due to the energy stored in the starter of the vehicle.
