A multi-functional activity management system for elderly utilizes prior art walking sticks to manage big data related to activity of elderly persons. In addition, new improvements have been made upon prior art walking sticks. By incorporating umbrella function into the walking stick, the stem portion becomes narrower and shorter, thereby making it easy to be inserted into the thin walking stick.

An electronic assembly for a remote-control device for a motor vehicle includes an electric power source and a supercapacitor block. The supercapacitor block has one or more supercapacitors, and said supercapacitor block is arranged in parallel with the electric power source. Additionally, a transmitter/receiver is connected to the supercapacitor block and a frequency amplifier stage is connected to said transmitter/receiver.

A cupped structure formed by walls having a cup shape are fastened to a radio to surround at least the speaker area of the radio with the walls. The sound is allowed to exit the radio through cupped structure. The sound exiting the cupped structure is amplified.

An ID transmitter for authentication on an access control unit of a physical unit. The ID transmitter may include an ID transmitter-BLE interface with an antenna, a microcontroller, a switching apparatus and a battery compartment to accommodate a battery. The microcontroller is arranged, in response to the receipt of the switching signal, to trigger the sending of an authentication signal that includes authentication information, and that is configured as a BLE beacon data packet. A set for assembling an ID transmitter and a system including an ID transmitter and a physical unit are disclosed.

A radio antenna interface for a portable radio is provided comprising a radio housing having a control top with a circular walled control top opening for receiving an antenna, the circular walled control top opening having an interior surface with a protruding bumper feature formed thereon. An antenna having has a base portion for insertion into the circular walled control top opening, the base portion has a ring feature forming a full circumference bump around the base portion. Once the antenna is assembled with the portable radio, the ring feature is located beneath and abuts with the protruding bumper to form the radio antenna interface. The radio antenna interface provides increased friction to minimize loosening of the antenna under extreme usage conditions.

The invention relates to a telecontrol (TEL) for the locking/unlocking and the starting of a motor vehicle comprising: an electronic circuit (ELEC) comprising at least one pathway comprising an input pin (BE) and an output pin (BS), a first radiofrequency antenna (ANT1) comprising a first loop disposed in the plane of the electronic circuit (ELEC), a second radiofrequency antenna (ANT2) comprising a second loop disposed in the plane of the electronic circuit (ELEC), said second antenna (ANT2) comprising: an input connector (CE) connected to the input pin (BE), an output connector (CS) connected to the output pin (BS), a tuning capacitor (C) linked to the electronic circuit (CIRC), for tuning the second antenna (ANT2) to a tuning frequency, characterized in that it comprises: an inductive input component (COMP_E) placed between the input connector (CE) and the input pin (BE), and/or an inductive output component (COMP_S) placed between the output connector (CS) and the output pin (BS).

An electronic device comprises: a battery; a communication module including a first processor; and a second processor electrically connected to the battery and the communication module. The first processor detects a transmission event of a Tx signal; requests voltage level information about the battery from the second processor in response to detecting the transmission event of the Tx signal; and receives the voltage level information about the battery from the second processor in response to requesting the voltage level information about the battery. The communication module compensates for the transmission power level of the Tx signal on the basis of the voltage level information about the battery received by the first processor.
