Abstract:
A method and apparatus that enables the load applied to a battery to be regulated. Regulation of the load to the battery is based upon a load request from which a set-point is derived in a microprocessor. From this set-point, voltage is either allowed to pass or not to pass through a regulator.
Abstract:
An engine starter motor tester applies power to a motor under test at the level normally applied while that motor is installed in a vehicle and monitors the ripple in the driving current. The ripple rate, scaled by the number of windings used in the construction of the motor, provides a direct reading of the shaft speed of the unloaded motor. This number allows a valid inference concerning the state of health of the motor, and is more certain than an estimate for an unloaded motor based on operator experience and motor “sound”. A complete test apparatus includes a stored lookup table, allowing the user to key in a product brand and model number and read directly both the RPM and the test apparatus's rating of the motor under test, expressed in terms such as percentage of life remaining.
Abstract:
A method and apparatus for automatically sensing the temperature of a battery during the testing and charging. The method and apparatus can monitor the temperature of the battery, the charger or both. Additionally, a user can be notified when the temperature is at or exceeds a predetermined level. The temperature data is also used to aid in efficiently charging the battery.
Abstract:
An alternator and starter tester system having a starter current zero test. The current is measured before and after a solenoid of a starter motor is energized and deenergized to determine if the starter motor should be failed. This allows the operator to quickly determine if the starter motor is stuck on during normal starter motor testing.
Abstract:
An alternator and starter motor tester system having alternator cable check. The alternator cable connector is specific to an alternator type. The cable connector is monitored so that if it fails a certain alternator type for a predetermined number of times in a row, the cable will be locked.
Abstract:
An method and apparatus testing an alternator and/or starter assembly including a power source for energizing the alternator and/or starter, a computer processor for monitoring electrical current supplied to energize the alternator and/or starter wherein the computer processor also monitors electrical voltage across the alternator. The invention also includes a first switch coupled to the computer processor which is enabled if excess current is required to energize the alternator; a second switch coupled to the computer processor which is enabled to place a heavy load on an output of the alternator if the voltage exceeds a maximum limit; a third switch coupled to the computer processor which is enabled if the current supplied to energize the starter exceeds a maximum limit.
Abstract:
An alternator and starter tester system having a bar code reader. The bar code can contain information regarding the component being tested and can direct the tester to conduct the appropriate test. The bar code can also encode the results of the test on a second bar code. The second bar code can then be coupled to the tested component.
Abstract:
An apparatus for holding a starter motor for testing has a base, a first pad mounted to the base that provides a support rest to a first side of the starter motor, a ratcheting arm having a second pad for contacting a second, opposite side of the starter motor, and a pivotal ratchet assembly to grip the starter motor between the two pads.
Abstract:
An apparatus for supporting an alternator for testing has a base, a turret having a socket defined therein, and a holding pin having two ends with a head at one end adapted to be inserted into the socket and retained therein. An elongated extension portion extends from the turret when the head is inserted in the socket, and engages with a portion of the alternator.
Abstract:
A plug-in module adds functionality to a portable electronic device. The module includes a housing that is accepted by a housing port of the portable electronic device. The module includes at least one latch to secure the module to the electronic device. Each latch includes a first member, a second member, and a third member. The housing includes at least one receptacle corresponding to each latch. The receptacles are sized and positioned to accept a member of the latch and direct the latch to a groove located on the portable electronic device. Optionally, the latch includes a slip-resistant surface sized to accept a human finger or thumb. The module also preferably includes a hardware interface connector sized and positioned within the housing to engage a 120-pin hardware interface port on the portable electronic device when the module housing is positioned on the housing port of the portable electronic device. Receptacles of the electric connector have certain functionality corresponding to the pins on the port.
