  • Publication number: 20200008857
    Abstract: Aspects of the present disclosure are presented for a surgical instrument for cutting and sealing tissue. In some embodiments, the surgical instrument includes a handle assembly, a shaft, and an end effector. The end effector may include: a blade that vibrates at an ultrasonic frequency, a shielded portion enclosing a back edge of the blade, a high-friction surface coupled to the shielded portion and positioned between the shielded portion and the back edge of the blade. A space is defined between the high-friction surface and the back edge of the blade when the end effector is in a cutting configuration. In a sealing configuration, the high-friction surface contacts the back edge of the blade, which generates heat based on ultrasonic vibrations of the blade rubbing against the high-friction surface. The shielded portion can coagulate bleeding tissue based on heat transfer from the high-friction surface to the shielded portion.

  • Patent number: 10425128
    Abstract: A system for transmitting data between components of an industrial vehicle that are powered by electricity received through a power line is provided. The system includes a first electrical choke with a conductor arranged to pass through the first electrical choke and to connect a first component to the power line, and a first communication circuit for at least one of sending and receiving signals and having a transmission wire for carrying the signals. When the first communication circuit transmits a communication signal, the communication signal passes along the transmission wire through the first electrical choke in a first direction, and subsequently the communication signal passes along the conductor through the first electrical choke in a second direction opposite to the first direction thereby cancelling attenuation of the communication signal by the first electrical choke.

  • Publication number: 20190247082
    Abstract: A surgical apparatus comprises a body, an ultrasonic transducer, a shaft, and an end effector. The ultrasonic transducer is operable to convert electrical power into ultrasonic vibrations. The shaft couples the end effector and the body together. The end effector comprises an ultrasonic blade in acoustic communication with the ultrasonic transducer. The ultrasonic blade includes a recess region having a plurality of recesses. The recess region is tapered such that the cross-sectional area of the recess region decreases along the length of the recess region. The ultrasonic blade is also curved such that a central longitudinal axis of the ultrasonic blade extends along a curved path. A reference circuit is used to account for voltage drops of unknown values during operation of the surgical apparatus.

  • Publication number: 20140278621
    Abstract: A facility management computer system is automatically configured when a material handling asset, such as a lift truck, is installed at the facility. A memory stores metadata comprising an asset identification and data specifying characteristics and parameters of the asset that are necessary or desirable in order to enable the facility management computer system to utilize the asset and perform functions, such as assigning work tasks, evaluating asset performance, and scheduling maintenance and repairs, for example. During asset installation the memory is electrically connected to facility management computer system. Upon that connection, the metadata are transferred automatically from the memory into the facility management computer system. Thereafter, the facility management computer system uses the metadata to manage operation of the material handling asset.

  • Publication number: 20140088837
    Abstract: A vehicle includes a vehicle frame, a vertical mast coupled to the vehicle frame, and a carriage movably mounted to the mast for ascending and descending along the mast. At least one hydraulic cylinder moves the carriage along the mast, a hydraulic pump pumps hydraulic fluid into the hydraulic cylinder, and a flow valve controls the flow of hydraulic fluid between the hydraulic pump and the hydraulic cylinder. A sensor senses an actual descent speed of the carriage and a controller controls the flow valve to allow descent of the carriage at a requested descent speed. The controller controls the flow valve to limit descent of the carriage to a unsolicited descent speed limit if a difference between the actual descent speed and the requested descent speed exceeds a threshold value.

  • Publication number: 20130338885
    Abstract: Operation of the industrial vehicle is managed by devices onboard the vehicle. One such management device includes a portable memory device issued to a person authorized to operate the vehicle. The vehicle control system, by reading data from the portable memory device, determines whether the person is permitted to operate that particular industrial vehicle and if so enables that operation. Another management device transmits a data signal through a power line on the industrial vehicle and uses a magnetically permeable wire bead in a unique manner to negate a short circuit effect that a component has on the data signal transmission. A further management device includes a module to interface a data acquisition module, designed to connect to a communication network of one type of industrial vehicle, for use with other vehicles.

  • Publication number: 20030080621
    Abstract: An automotive electrical system protection device protects the wiring of a direct current electrical system should a short circuit scenario occur. Moreover, the same protection device independently detects and guards again battery voltage depletion due to low current drain or run-down caused by faulty accessory loads or such loads being left on after the engine of the vehicle and associated generator are shut-off. The protection device has a run-down relay which opens upon prolonged low current conditions which causes battery voltage to deplete below a threshold voltage necessary to start the engine. Upon starting of the engine, the run-down relay, if open, will automatically close to permit power to the starter motor. During high current or short circuit conditions, a high current relay will open to protect the wiring of the electrical system including that of a primary conductor wired directly between the battery and the starter motor.
