A hybrid gamma–beta voltaic device designed for direct conversion of radiation from nuclear waste into electricity. The invention employs alternating PbO and SiC semiconductor layers reinforced with hollow copper rods acting as both electrical conductors and coolant channels. Gamma and beta radiations are absorbed and converted into charge carriers through photoelectric and betavoltaic effects. The generated charge is collected via copper channels, with heat managed through a passive coolant loop. The assembly is fully shielded, providing a long-life, maintenance-free system for nuclear waste energy recovery.

[Problem] To prevent employees from experiencing excessive stress, a camera unit is attached to the employee to record their interaction with customers, and a camera system is provided that suppresses customer outbursts by making the customer aware that they are being filmed. [Solution] The camera system (1) consists of a camera unit (12) that films a person and generates video data, mounted on a housing (10) that can be attached to at least the surface of clothing (B). In particular, a display screen capable of displaying video data is provided on the housing (10) on the same plane as the lens surface of the camera unit (12), and by displaying the video data on the display screen, the person being filmed can be made aware that they are being filmed by the camera unit (12).

Techniques pertaining to data allocation for joint data communication and sensing in mobile communications are described. An apparatus (e.g., a user equipment (UE) ) generates a plurality of orthogonal frequency-division multiplexing (OFDM) symbols carrying data. The apparatus then transmits the plurality of OFDM symbols to: (a) communicate the data; and (b) perform mono-static sensing based on the plurality of OFDM symbols. A constraint is applied to at least one OFDM symbol of the plurality of OFDM symbols.
