摘要:
A miniaturized communications unit for use in object tracking, control and the like. Each communications and identification unit repeatedly transmits an identification code on a predetermined wavelength at a transmission interval randomly selected from within a predetermined time interval range in order to avoid repeated transmission collisions between two or more units. The transmission may further include data corresponding to a sensed environmental attribute. Each unit that receives a transmission stores the received identification code and any data in a time ordered record. This stored record preferably also includes an electronic date and time stamp. The stored data can be transmitted to an external data port for later use or analysis by an external data processor. The preferred construction of these communications and identification units includes a programmed microprocessor circuit with the program preferably stored in an electrically programmable read only memory for the sake of flexibility and ease of alternation.
摘要:
A vehicle includes an internal combustion engine, a first hydraulic pump/motor coupled with the internal combustion engine, and a second hydraulic pump/motor is coupled with at least one driven wheel of the vehicle. A clutch establishes a driving connection between the first hydraulic pump/motor and the internal combustion engine, and selectively interrupts the driving connection when disengaged. At least one vehicle accessory device is coupled to the first hydraulic pump/motor. The at least one vehicle accessory device is operable under power of the internal combustion engine when the clutch is engaged and the internal combustion engine is running, and the at least one vehicle accessory device is operable directly by the first hydraulic pump/motor operating in a motor mode when the clutch is disengaged, regardless of whether or not the internal combustion engine is running. A corresponding method of operating the vehicle is also provided.
