| 20090039898 | Alternator and starter tester with alternator cable check - 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. | 02-12-2009 |
| 20090125179 | METHOD AND APPARATUS FOR MONITORING BATTERY DRAIN AND STARTER CURRENT - A parasitic drain tester measuring the parasitic battery drain of a vehicle and the high current used by the vehicle starter motor, includes a current measuring circuit and a unit. The current measuring circuit includes a capacitor smoothing the current distribution within the circuit, a first interface connected to a vehicle power source being tested and the capacitor, a second interface accommodating an outside connection for communication, a first processor connected to the second interface and the capacitor, the processor communicating with the second interface and performing analysis and calculation of the data received, and a converting unit connected to the processor, converting the signal received through the first interface from a first form to a second form in order to process the signal received. The first unit is connected to the current measuring circuit, and the first unit includes a memory storing information retrieved from the current measuring circuit through the second interface, and a second processor analyzes the information received from the current measuring circuit and providing instructions to the first processor through the second interface. | 05-14-2009 |
| 20090249868 | Starter Zero Current Test Apparatus and Method - 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. | 10-08-2009 |
| 20090265057 | USB Isolation for Vehicle Communication Interface - The present invention relates generally to an automotive diagnostic tool which facilitates data communications between an automobile and diagnostic device, such as a personal computer. More particularly, the present invention relates to electrically isolating the data communications using a Vehicle Communication Interface (VCI) device situated between an automobile's communication diagnostic port and the personal computer. The VCI contains logic circuitry to translate the automobile's On Board Diagnostic (OBD II) signals to an embedded Ethernet controller. Ethernet signals are then non-galvanicly exchanged with an Ethernet to USB controller with an Ethernet transformer. A personal computer is attached via a USB cable to the VCI's Ethernet to USB Controller, permitting information exchange between the automobile and the personal computer. | 10-22-2009 |
| 20090276117 | Simultaneous Vehicle Protocol Communication Apparatus and Method - A diagnostic tool for simultaneously communicating with a plurality of motor vehicle control units and implements at least two different communication protocols within a single motor vehicle. The diagnostic tool includes a processor and a field programmable gate array. The processor simultaneously executes a plurality of diagnostic routines and thereby provides messages to at least two of the plurality of motor vehicle control units. The field programmable gate array provides a selectable multiple protocol interface to simultaneously accommodating the at least two different communication protocols. The field programmable gate array is coupled between the plurality of motor vehicle control units and the processor. The selectable multiple protocol interface simultaneously converts the messages from the processor into a format readable by the selected motor vehicle control units and simultaneously converting received control unit information into a format readable by the processor. | 11-05-2009 |
| 20090289756 | Diagnostic Connector Power for Tablet/Laptop PCs - An adapter for coupling a vehicle communication interface device and a computer processing device to a signal source comprises a first port configured for communication with the communication interface device and a second port configured for communication with the computer processing device. The adapter can include a receptacle configured to receive signals having a data portion and a power portion. The adapter can further identify the received signals as being one of vehicle signals or computer signals. Moreover, the adapter can include a relay having a first state associated with the vehicle signals for relaying the vehicle signals between the first port and the signal source and a second state associated with the computer signals for relaying the computer signals between the second port and the signal source. The relay can be selectively placed in one of the first and the second states associated with the received signals as identified by the receptacle. | 11-26-2009 |
| 20090292414 | UNIVERSAL VEHICLE INPUT/OUTPUT TRANSCEIVER AND METHOD OF OPERATION THEREOF - A vehicular diagnostic tool configured to interface with a plurality of vehicular computing systems that each utilize a different communications protocol. The tool includes a transceiver that itself includes a voltage threshold controller and a current threshold controller. Also, a method of using a single vehicular diagnostic tool to communicate with a plurality of vehicular computing systems that each utilize a different communications protocol. | 11-26-2009 |
| 20100101312 | Apparatus and Method for Starter RPM Detection - 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. | 04-29-2010 |
| 20100153039 | Apparatus and Method for Testing a Power Source - A method and apparatus for communicating a battery information to a remote device or database. The battery tester and/or charger can communicate with a wired or wireless connection to the remote device. Battery indentifying information, test results and warranty information can be communicated to the remote device or database. | 06-17-2010 |
| 20100170944 | Alternator and Starter Tester with Bar Code Functionality and Method - 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. | 07-08-2010 |
