A two mode power-split electric hybrid system and a method of control said hybrid system. The hybrid system is comprised of an engine, a transmission, an energy storage device and a control system for effecting said control method. Said transmission is a reconfigurable power split system, comprising a power-splitting device and an output power path selecting device. The power splitting device includes a compound planetary gear system and two electric machines which form a local series electric hybrid system. Said transmission regulates the output power state of said hybrid system by controlling power flow within said local series hybrid system. The hybrid system provides at least two operating mode, an output power split mode and a compound power split mode. Said control system includes multiple controllers and control modules. In accordance with the operating conditions of the hybrid system, said control system computes and sets system power requirement, allocates ob board power resources and sets engine operating speed and torque. In addition, said control system sets the operation mode of the transmission and controls the engine speed by adjusting operating torque of electric machines, based on the differential signal between reference engine speed and actual engine speed. Said control system is also capable of controlling engine torque through engine controller.

Parallel printing systems and methods incorporate inverter assemblies for not only inverting media during transport through the system but also to register the media or provide a velocity buffer transports with different drive velocities. The inverter assemblies can include the capability to optionally deskew the media and provide lateral registration corrections. The inverter assembly nip rollers are sufficiently spaced from process drive nip rollers to decouple a document in the inverter assembly from the highway paths. The method comprises combining the inverting function selectively with either the registering or the velocity buffering functions.

A pumping machine, that can serve a system as the sole main pump for pressurizing a primary liquid flow, incorporates, in a single machine, a rotor-drum type AP (axial piston) pump and a PX (pressure exchanger) that recovers energy from a secondary liquid flow such as the brine discharge from an RO seawater desalination system, with benefits including fewer moving parts and small machine size along with lower capital and operating costs. A single rotor-drum containing the cylinders and pistons is located between two end blocks, one or both configured with manifold passageways, ports and sliding valves. A swash-plate at one end reciprocates the pistons axially when the rotor-drum is rotated. Two working chambers, primary and secondary, are formed at opposite ends of a single piston in each cylinder, thus enabling the single rotor-drum to function as a primary liquid-pressurizing axial pump (AP) with sliding valves at the primary end enabling primary liquid pumping, and as a secondary outflow-driven pressure exchanger (PX) recovering energy from pressure drop in the secondary liquid flow and thus contributing work to primary pumping, saving energy and reducing operating costs.

A wireless power supply apparatus includes a power reception coil, an actual load and an auxiliary load. The power reception coil functions as a repeater for receiving electric power in a non-contact manner by magnetic resonance with a power transmission coil to which electric power is supplied from a power supply unit and relaying transfer of the electric power from the power transmission coil. The actual load is connected to the power reception coil and is powered by the electric power received by the power reception coil. The auxiliary load is inserted parallel to the power reception coil and the actual load and forms a closed circuit with the power reception coil when supply of the electric power to the actual load is interrupted to be in an open state.

A portable IGBT (Insulated Gate Bipolar Transistor) of high reliability, compact size, and low cost includes a main circuit to which a control circuit and an auxiliary power supply circuit are connected. The main circuit includes, in sequence, an input rectifier filter circuit, an inverter circuit, a high-frequency primary transformer, and a secondary output rectifier circuit. The control circuit includes a PWM regulation circuit, an IGBT driving circuit, a current feedback circuit, and a current setup circuit. The inverter circuit includes a full-bridge hard switching structure, which has IGBTs constituting bridge arms that are sequentially conducted, so that their alternating conduction converts direct current into high frequency square wave alternating current, which flows through the high-frequency primary transformer and is then subjected to rectification to supply an output of low voltage direct current. Each IGBT is connected in parallel to resistor and capacitor, which constitute a peak voltage absorption circuitry.

A device (1) for machining an ophthalmic lens includes a support for the ophthalmic lens and for driving it in rotation about a blocking axis (A1), a machining module (35) that can be swiveled relative to the support and driving the lens in rotation and that is suitable for pivoting about a swivel axis that is not parallel to the blocking axis of the lens, and at least one drill tool mounted to rotate on the machining module about a first axis of rotation. The machining device includes at least one other machining tool mounted to rotate on the machining module about another axis of rotation that is distinct from the first axis of rotation and that is stationary relative to the first axis of rotation.

This invention is a reduced size citrus fruit juicing machine that uses sets of rotating male-female drums characterized by having one sole female drum and one sole male drum with an automatically positioning blade and a retaining pendulum—turning device. These characteristics avoid having to incorporate a second set of drums into the machine since the remaining half of the fruit is turned after the cut into the following upper cavity of the female drum. In addition to maintaining the performance of similar machines of greater size, it improves hygienic conditions due to an appropriate disposition of the retaining pendulum, a ribbed opening for the fruit, a peel collector and an integrated customized juice container which are isolated from the outside, all of which make it especially attractive to hotels and restaurants that do not have much available space.

An object of the present invention is to provide a gear measurement method which makes it possible to reduce the size of a machine by reducing the amount of travel of a probe and thus reducing a moving range of the probe in a measurement. To achieve the object, a gear measurement method for measuring the tooth profile of a workpiece (W) by linearly moving a probe (16a) in accordance with the rotation of the workpiece (W), with the probe (16a) in contact with a right tooth face (WR) or a left tooth face (WL) of the workpiece (W), by synchronous control of the movement of the probe (16a) and the rotation of the workpiece (W), includes setting a tangent line (L) touching the tangent point (A) rotated from a tangent point (Ao) on the base circle (Wb) of the workpiece (W) in one direction by a predetermined rotation angle (α) and a tangent line (L′) touching the tangent point (A′) positioned by being rotated from the tangent point (Ao) on the base circle (Wb) of the workpiece (W) in the other direction by the predetermined rotation angle (α), moving the probe (16a) along the tangent line (L) when measuring the right tooth face (WR), moving the probe (16a) along the tangent line (L′) when measuring the left tooth face (WL), and setting the respective midpoints of the segments connecting the measurement start points (B, B′) to the measurement end points (C, C′) at the intersection point (M) of the tangent lines (L, L′).

An intermittent excitation apparatus of a 3D printer includes at least one guide, a drive rod, a movable seat, and a microcontroller. When the microcontroller controls a first motor in a non-excitation and non-rotation condition, the movable seat is fixed on the drive rod and the 3D printer performs a plane printing operation. When the microcontroller controls the first motor in an excitation and rotation condition, the movable seat moves along the drive rod. Therefore, it is to significantly reduce heat generated inside the first motor, decrease costs, and reduce the size of the 3D printer.
