摘要

The shooting target has a target disc (3) enclosed by an outer frame (1) and provided by an endless band (42). This has at least two target disc images, moved into the target image plane via a motorised drive, in alternation.

The centre of the target disc is covered by a second endless band (41), with automatic positioning of the disc image band relative to the target disc via the setting motors (46). These are controlled via an electronic evaluation stage (44), coupled to sensors (43) for detecting the position markings (45) carried by the disc image band.

ADVANTAGE -Protects centre of target disc image by second endless band, giving increased replacement time interval.

[0001]BACKGROUND OF THE INVENTION

[0002]Health and performance monitoring of machine becomes a major avenue in machine smart controlling. Health Monitoring of machines allows detecting critical faults before they occur. Autonomous machines allow the machine to perform based in a changing environment without the need for human intervention. In most cases the power for monitoring health or performance comes from the machine power source. Yet, in some cases the location of the monitoring sensor is at places where power cannot be supplied. Among such cases are rotating parts such as belt on a pulley and washing machine drum, automotive wheel and alike.

[0003]SUMMARY OF THE INVENTION

[0004]This patent application is related to rotation energy harvester that harvests electric power from rotation of bodies. The harvested energy may be used to power sensors for health and performances monitoring and RF communication for data transmission and RF control.

FIGS. 3 a and 3 b depict an embodiment of Rotation Energy Harvester for a rotating belt. FIG. 4 depicts an embodiment of Rotation Energy Harvester for a washing machine. FIGS. 5 a and 5 b depict the Rotation Energy Harvester for a washing machine.

[0006]DETAILED DESCRIPTION OF THE INVENTION

[0007]This patent application is related to harvesting electric power from rotation of bodies. Specifically, for harvesting electric power from rotation in cases where electric devices are placed on a rotating body without a line power source. In such case a battery may be used with limited lifetime and performance that are dedicated by the available battery capacity. The harvested energy described in this patent application comprise a at least one coil fixed to the rotating part and at least one magnet fixed to the chassis of the body such that during rotation the coil passes close to the magnet that induces voltage drop between the coil ends. The coil wire can be wound around a core such that the core passes close to the magnet that induces voltage drop between the coil ends

[0008]Equation 1 describes the Electromotive force measured in volts developed between the coil ends.

[0009]E = - N · d ⁢ Φ / dt ( 1 )

[0010]N is the number of turns of the coil, and Φ is the magnetic flux. Moving a magnet relative to a coil generates dΦ/dt. Clearly the large dΦ/dt the larger E and therefore the higher the rotation speed of the rotating body the higher the generated electric power.

[0011]FIG. 1 is a general embodiment of a Rotation Energy Harvester of a moving body ( 2 ) that cyclically moves relative to a stationary body ( 4 ). In this embodiment, module ( 1 ) is fixed to the moving body, and module ( 2 ) comprise at least one magnet fixed to the stationary body such that the magnetic poles are along the moving direction of the moving body. Module ( 1 ) includes an electromagnetic device ( 11 ) and an electric circuit ( 12 ). The electromagnetic device ( 11 ) may comprise at least one element ( 111 ) that may be coil ( 110 ) with two ends ( 1101 ) and ( 1102 ) as shown in FIG. 1 b or at least one core ( 11103 ) winded by a coil ( 110 ) with two ends ( 1101 ) and ( 1102 ) as shown in FIG. 1 c . The coils from different elements ( 111 ) may be connected to each other in serial or in parallel such that two terminals ( 1111 , 1112 ) emerge from the module that are fed to the electric circuit. As the moving part ( 3 ) moves relative to the stationary part ( 4 ), device ( 1 ) moves relative to the magnet ( 2 ) such that voltage drop develops between terminals ( 1111 ) and ( 1112 ).

[0012]One embodiment of the electric circuit ( 12 ) is described in FIG. 2 . The modules comprise a power management ( 121 ) that rectifies the voltage generated between terminal ( 1111 ) and ( 1112 ) and manages the electric properties such that the generated power is suitable to power an electric storage device ( 122 ), and devices such as sensors ( 123 ) and RF communication device ( 1024 ). The electric storage device may be for example a rechargeable battery or super capacitor.

[0013]FIG. 3 describes a rotation energy harvester comprising modules ( 1 ) and ( 2 ) described in FIGS. 1 and 2 . Module ( 1 ) is fixed to a rotating belt and module ( 2 ) is fixed a stationary body ( 4 ). The harvested energy powers sensors that monitor the health of the belt and the forces applied on the belt.

[0014]FIGS. 4 and 5 , describe a washing machine ( 41 ) with a rotation harvester ( 1 ), ( 2 ) described in FIGS. 1 and 2 . In the embodiment shown in FIGS. 4 and 5 , the magnet ( 2 ) is connected to the washing machine ( 41 ) through a metal bridge ( 4 ). Device ( 1 ) is fixed to the washing machine drum ( 3 ). The harvested energy powers sensors that monitor the health of the washing machine, the forces applied on the drum and properties of the washing cycle.
