Abstract: A ball dropping tool includes an outer and inner body, side bore, ball and an actuator. The outer body has an axial bore extending between a first and second end of the outer body and forming a flow path. The inner body forms a bypass passage extending between a first and second end of the inner body. The side bore is defined by the inner body and is disposed at an angle relative to the axial bore of the outer body. The bypass passage is disposed in a portion of the flow path and is in communication with the side bore. The ball is disposed within the side bore. The actuator, disposed within the outer body, is movable between a retaining position wherein the ball is retained within the side bore and a release position wherein the ball is released from the side bore and into the bypass passage.

Abstract: Ultrasound imaging is a non-invasive, non-radioactive, and low cost technology for diagnosis and identification of implantable medical devices in real time. Developing new ultrasound activated coatings is important to broaden the utility of in vivo marking by ultrasound imaging. Ultrasound responsive macro-phase segregated micro-composite thin films were developed to be coated on medical devices composed of multiple materials and with multiple shapes and varying surface area. The macro-phase segregated films having silica micro-shells in polycyanoacrylate produces strong color Doppler signals with the use of a standard clinical ultrasound transducer. Electron microscopy showed a macro-phase separation during slow curing of the cyanoacrylate adhesive, as air-filled silica micro-shells were driven to the surface of the film. The air sealed in the hollow space of the silica shells acted as an ultrasound contrast agent and echo decorrelation of air exposed to ultrasound waves produces color Doppler signals.

Abstract: A method is provided to detect a lost packet in an event-based communication system which uses a communication protocol without error correction or recovery. The method includes maintaining a plurality of counters for tracking an overall count of data packets transmitted, and a count of data packets transmitted for each event-type; and transmitting a sequence of data packets to at least one remote device. Each data packet includes information of an event-type from the plurality of different event-types and count information associated with the counters. The method further involves receiving a message from the at least one remote device that at least one data packet from the sequence of transmitted data packets is lost based on the count information from at least one transmitted data packet; and taking at least one action in response to the message.

A syringe housing assembly is selectively connectable to the handle assembly and includes a syringe housing and a tubular syringe sleeve telescopically received through a distal end of the syringe housing and axially movable with respect thereto. The syringe housing has an exterior side surface surrounding a syringe housing interior configured to receive at least a portion of a syringe. The syringe sleeve has a proximal end, a distal end with a skin contact surface, and a generally cylindrically-shaped outer surface.

Abstract: A motorized supplemental trailer axle includes an axle securable to a trailer and having a wheel affixed to opposing ends thereof. A motor for powering the axle wheels is operably connected to a battery power supply. A transfer case having a clutch mechanism is operably connected to the motor and the axle, wherein the clutch mechanism is configured to selectively engage the motor with the axle to rotate the pair of wheels. A control module includes a sensor configured to monitor rotational speed of the pair of axle wheels, a processor, a non-transitory computer readable medium operatively connected to the processor, and a logic that, when executed by the processor, causes the system to calculate a wheel speed of a vehicle currently towing the trailer and activate the motor to rotate the wheels of the trailer axle at a speed that matches the towing vehicle's wheel speed.

Abstract: A chair can include armrest apparatuses. Each of the armrest apparatuses can be configured so an arm pad is connectable to an armrest without the use of a mechanical fastener (e.g. a screw, a bolt, etc.) and without the use of an adhesive or welding, and without the use of mechanical tools (e.g. screw driver, hammer, etc.) by use of interlocking mating profiles defined in the structure of the arm pad and structure of the armrest to which the arm pad is attached. Embodiments of the chair can be configured as a side chair, task chair, or other type of chair having at least one armrest or other type of armrest apparatus.

Abstract: A chair can include a chair back, or backrest, that is coupled to a base of a chair above a seat of the chair. A tilt mechanism can attach the backrest to the base at spaced apart locations. In some embodiments, the tilt mechanism can be configured so that the backrest rotates about multiple pivots as it reclines from an upright position to a reclined position to drive forward motion of the seat during recline of the backrest.
