摘要:
An apparatus for a circuit which allows a user to connect various adaptors to a common interface to provide a device with power and data signals. The circuit may provide a device, in which the circuit is incorporated, with the ability to discern whether a connected adaptor is providing power or data at any given time. If the adaptor is providing power at a particular moment, then the power/data circuit can identify that power is being provided and signal the device to accept power. When the adaptor is providing data at a particular moment, then the circuit can identify that power is being provided and signal the device to accept power. The circuit may include a power/data input, a vehicle connector, an internal power source connector, a reference voltage source, a comparator, and sensor.

A service hose includes a service coupler and a check valve assembly. The service coupler is configured to fluidly connect the service hose to a refrigeration system. The check valve assembly is disposed proximal to the service coupler and includes a recovery and a recharge flow path. The recovery flow path is defined by a flow of a refrigerant from the refrigeration system and flows along a first bore disposed in a body having a recovery poppet. The recharge flow path is defined by a flow of the refrigerant to the refrigeration system and flows along a second bore disposed in the body, a recharge poppet, and a biasing member. The check valve assembly is configured to provide a substantially free flow of refrigerant along the recovery flow path and also configured to provide a predetermined cracking pressure in response to the refrigerant being urged to flow along the recharge flow path.

A refrigerant recovery system includes a recovery apparatus and a refrigerant recovery unit. The recovery apparatus includes a heat sink, a capture tank, and a hose. The capture tank is in thermal contact with the heat sink. The capture tank is configured to capture a first refrigerant from a refrigeration system. The hose is to fluidly connect the capture tank to the refrigerant system. The refrigerant recovery unit includes a refrigerant storage unit, a refrigerant circuit, a processor and a memory. The refrigerant storage unit is configured to store a second refrigerant. The refrigerant circuit is in fluid connection with the heat sink. The refrigerant circuit is configured to circulate the second refrigerant through the heat sink, a compressor, and a condenser. The processor is configured to control the refrigerant recovery unit. The memory is to store diagnostic software and operating software to operate the refrigerant recovery unit.

A load supporting stand that having a longitudinal axis is disclosed. The supporting stand has an upper column that includes a shaft having a first end and a second end that extends along the longitudinal axis. The shaft has a first diameter. The upper column also includes a shelf attached to the first end of said shaft. The upper column also has a load bearing pin that extends transversely through the shaft. The stand also has a base portion that receives the upper column that includes a receiving conduit that extends along the longitudinal axis and has a second diameter greater than the first diameter. The conduit has a third end and a fourth end and a slot that extends between the third and fourth ends along with a series of notches extending therefrom. The base portion has a base plate connected to the receiving conduit.

A system and method for automating the selection of vehicle identifying information for a diagnostic tool and for searching multiple databases of fix information and providing such information to a user.
摘要:
A diagnostic tool and method are provided wherein a faulty part and its part number is determined based on a retrieved DTC for a specific vehicle. The part number may include the original manufacturer's number and a generic equivalent manufacturer's number (if available). The diagnostic tool can search a parts database of various parts suppliers for their pricing and location. The diagnostic tool can also provide suggested fixes to the user based on the retrieved DTC.
摘要:
A system and method for an automotive diagnostic server can provide a portable vehicle diagnostic tool to identify a failed vehicle component. It may also provide a remote information device to serve as a connecting intermediary between devices, and to allow remote control of the devices and to provide information to a user. A remote diagnostic device to analyze data and interpret information to aid the user in making, using, maintaining, and fixing a piece of equipment or product may also be included. Web server functionality may be incorporated into the portable vehicle diagnostic tool to allow dissemination of the diagnostic information resulting from the diagnostic testing, and the web server may be accessed by a web browser of the remote information device.
摘要:
A method for converting a refrigerant recovery unit from use with a first refrigerant to use with a second refrigerant includes the steps of opening, with a controller, solenoids along a refrigerant path to remove residue of the first refrigerant into a holding vessel, operating a vacuum pump, as indicated by the controller, to further remove the residue of the first refrigerant from the refrigerant path, introducing, via the controller, an amount of the second refrigerant into the refrigerant path, determining, with a refrigerant identifier, a purity of the second refrigerant in the refrigerant path. A kit is also provided to convert the refrigerant recovery unit for use with the first refrigerant to the second refrigerant.

A compression tester adapter is provided. The compression adaptor includes a generally cylindrical plug fitting, including a pilot segment, an external thread, a cylinder segment, a gasket located between the external thread and the cylinder segment and a plug end; and a connector fitting including an attachment interface; and a hose attached to the plug fitting. A method of adapting a compression tester spark plug hose for use with a spark plug socket is provided. The method includes; engaging a threaded spark plug socket in an internal combustion engine cylinder head; attaching a compression tester spark plug hose; and transmitting a compressed gas to the compression tester spark plug hose wherein the spark plug socket thread is configured with a nominal diameter of 12 millimeters; and creating a substantially airtight seal against a periphery of a tapered seat near a inner extreme of the spark plug socket.

The present invention is directed toward a cellular phone that connects to an existing vehicle data link to perform the functions of an off-board device, such as a scan tool, for displaying diagnostic information relating to vehicles. In addition, the cellular phone connects to a starter/charger system and/or a battery to perform the functions of a starter/charger/battery testing device. Such a device allows a user to connect the cellular phone to a data link connector located in a vehicle, download software to either an adaptor or the cellular phone, retrieve information relating to diagnostic tests on the vehicle and view the results on the cellular phone display, and/or communicate the results to another person or device.
