A subsurface mounted inductive charging coil system for electric vehicles accommodates the gap distance between primary charging coil and secondary coil on the vehicle with an extendable primary coil carrier. The system protects the primary coil when exposed by mounting on a deformable and elastic structure. By keeping the primary coil normally hidden in a deformable and elastic structure several advantages are obtained. The extendable structure is preferably a low pressure inflatable bladder or membrane in the floor for carrying, protecting, and extending the primary coil.

A powered converter dolly for movement and attachment of trailers is provided. The dolly comprises a conventional converter dolly having a retractable landing gear assembly mounting wheels attached to the drawbar. The dolly has a power supply and operates as a towing device. The landing gear assembly provides steering for the dolly as well as motive power from a motor connected to the landing gear wheels. Alternatively, the wheels of the dolly may be powered for providing motion to the dolly. The dolly further comprises several attachment devices for securing the dolly to an intermodal railcar, including alternative hydraulic, mechanical, and electrically-powered tie down devices. A trolley movable along a railcar is provided for securing the dolly or trailer to the railcar and includes a hitch component for selectively interconnecting to a hitch component on the dolly or trailer.

A machine vision image acquisition system is provided with a housing or enclosure that protects the acquisition system components from an industrial environment. The machine vision image acquisition system has a focusing mechanism that can be actuated externally to the housing. The focusing mechanism uses a gear drive to transmit externally actuated focus adjustments to the optical components of the acquisition system.

A circuit and method is disclosed for measuring the resistance of a resistive sensor, such as a PTC or NTC temperature sensor used for monitoring the temperature of the windings of an electric motor. The measurement circuit is based on an electronic circuit in which conductors from a sensor located in the object to be monitored are connected to an amplifier circuit in a feedback configuration that reduces the DC level supplied to the voltage divider when the sensor resistance increases. The measured signal is amplified and, using a comparator to compare it with the output voltage of a sawtooth generator, a continuous PWM (Pulse Width Modulation) signal is generated and transmitted in digital format to a SELV electronic circuit, for example through an opto-isolator. The essentially logarithmic signal amplification makes it possible to reliably distinguish between a short circuit in the sensor circuit and low values of sensor resistance.

Fluid hoses associated with land vehicles, such as a truck, are supported on the vehicle by a spring-biased reel mounted beneath the truck. Desired tension is maintained on the hoses by the spring loading of the reel whereby the hoses are maintained in a desired location and position on the vehicle.

A personal electronic device storage apparatus includes a portable storage case including a body having a divider wall statically seated therein. A first cavity is disposed above the divider wall for containing the personal electronic device therein. A second cavity is disposed below the divider wall. A lead plate seated within the first cavity for preventing electromagnetic waves from passing through the body. First and second retractable cords are rotatably disposed within the second cavity, and first and second holders attached to distal ends of the first and second retractable cords respectively. At least one of the first and second holders may be capable of may be tethered to the personal electronic device. Such a structural configuration provides the unexpected and unpredictable advantage of shielding the personal electronic device from electromagnetic waves while keeping it tethered to the storage case.

A remotely controlled, motorized drive system for a disconnector used in switchgear. An operator pushes a button on a remote control, which signals a receiver in the disconnector to engage a motor that is coupled to a drive shaft. The drive shaft causes movable contacts of the disconnector to be moved into engagement or out of engagement with sets of fixed contacts in the switchgear that are connected to the line supply and to the circuit breaker that is bolted into the switchgear. One set of contacts is electrically coupled to the line supply, which can carry up to three phases of current. Another set of contacts is connected to corresponding terminals of the circuit breaker. A second motor controls movement of a grounding bar that grounds the circuit breaker to earth. Indicator lights on the switchgear panel indicate the position of the disconnector for visual confirmation of the same.

The invention discloses a stope micro-earthquake continuous monitoring intelligent early-warning instrument, which is characterized in that a micro-earthquake sensor sensing and collecting device is arranged at a stope access or in an adjacent drift roadway so as to monitor stope rock mass micro-fracture signals and collect the micro-earthquake time, the micro-earthquake frequency, the micro-earthquake energy, the micro-earthquake magnitude and the micro-earthquake location; a micro-earthquake signal processing system analyzes the collected data so as to carry out judgment on the stability state of stope rock mass and carry out recognition on a potential rock mass collapse hidden danger location of the stope; and an early-warning device carries out sound-light signal early warning on the stability of the stope rock mass. The stope micro-earthquake continuous monitoring intelligent early-warning instrument can perform monitoring on the stope rock mass stability, and carries out early warning on potential safety hazards such as roof collapse, wall caving and rock burst in a stope personnel operation area. Workers are enabled to check and process rock mass collapse hidden dangers in the stope personnel operating area timely, and safety accidents such as roof collapse, wall caving and rock burst can be effectively controlled and reduced.

We disclose a portable protection shelter that may be easily transported and set up as needed. The shelter provides protection from deadly weather, including storms, hail, hurricanes, and tornados. Additionally, it may be used as a survival pod or as protection from assailants or aggressive animals. The shelter can be transported as required, including through doors, and assembled and disassembled on demand using common handheld tools.

Step Ladder Safely Shoe provides security and stability for the base of a ladder and can prevent users from potentially falling off of an unstable ladder. This device acts as shoes (surface-area increasers) for the feet of a step ladder by providing four supportive units into which the ladder's feet can be placed. By using this product, individuals may be able to use a ladder without needing a second person to hold and stabilize the ladder, as well as allowing individuals to easily use the ladder with minimal effort on wet or soft ground.

A portable safety platform scaffold apparatus includes a plurality of wall-supportable units for being supported by the top portion of a wall. The wall support units each include a wall-top engagement portion, a common removable floor member, and a common removable fence. With the apparatus, a worker can stand on the floor members with the wall-top engagement portions secured on the top of the wall. In this way, the worker is in a safe location when a roof truss is lowered onto the wall.

A safety platform scaffold apparatus is provided having a plurality of wall-supportable units, each with a floor support portion. A work platform is removably mountable on the floor support portions by suitable connectors affixed to the opposed ends of the platform. The opposed connectors are complimentary to each other so that they can be nested together on the same floor support portion thereby enabling a multiplicity of wall supportable units to be mounted on a wall with juxtaposed side-by-side platforms defining a smooth, flat, continuous work surface and wherein the platforms interlock with each other and the wall-supportable unit floor portions.
