  • Patent number: 10680677
    Abstract: The present invention provides for a system that makes use of a system power supply enable switch controlled by a near field communications (NFC) frontend with energy harvesting. In one embodiment, RF power in the 13.56 MHz band generated by a NFC counterpart (such as a mobile phone) is detected by the energy harvesting unit being part of the battery-unpowered NFC communication device. After activation, the system can perform actions required to communicate to the presented device (i.e., the NFC counterpart). Later, the system can switch itself into the unpowered state again. In another embodiment, this feature can also be used to control an NFC protection circuitry very quickly after the NFC device is exposed to an external HF (high frequency) field.

  • Patent number: 10357792
    Abstract: A dispenser for discharging liquid to pasty masses, has a pump head and a pump chamber, having a pump chamber wall and an inlet valve and an outlet valve. The pump chamber is formed by a bellows part, on which the inlet valve is integrally formed. The inlet valve is retained of retaining arms, which extend in the peripheral direction of the inlet valve and are connected to the pump chamber wall and to the inlet valve, and the inlet valve forms a peripherally extending valve lip, which freely protrudes in cross-section. The inlet valve extends in the shape of a circle segment in a longitudinal cross-section of the bellows part, having an upper dome segment and the lower valve lip. The connection to the retaining arms is formed at a height center of the inlet valve or at an offset therefrom toward a free edge of the valve lip.
