Abstract: The invention relates to a shockproof power bank which includes a power bank body and a protective cover. The inside of the protective cover is divided into two layers, respectively a spring buffer layer and an air cushion buffer layer. A sleeve is fixedly connected to the inside of the spring buffer layer. A telescopic rod is fixedly connected to the inside of the sleeve. A bottom of the telescopic rod is fixedly connected with a baffle. A spring is provided between a bottom of the telescopic rod and a bottom of the sleeve. The other end of the telescopic rod penetrates the top of the sleeve and is fixedly connected with the protective cover. The bottom of the sleeve is fixedly connected with a connecting rod, and the inner surface of the air cushion buffer layer is fixedly connected with a regular hexagonal airbag. The four adjacent hexagonal airbags are fixedly connected with a diamond airbag.

Abstract: A wireless sensor module comprises: input means (2) for determining a target piece of information such as temperature. A transmitter (18) is arranged to transmit this information to a remote receiver (48) in discrete bursts. The module's power supply (4) comprises one or more photovoltaic cells (22) at least one capacitor (34) arranged to be charged by the photovoltaic cell(s) (22). The capacitor is further arranged such that it may power the transmitter (18).
