The invention relates to switch mode power supply modules and items of equipment powered by these modules. The power supply module comprises circuits for cyclically interrupting the switching operation, during a so-called switching operation interruption phase, if the load current of the module is less than a current threshold value and sustaining the switching operation, during a so-called switching operation phase, if the load current is greater than the load current threshold value and circuits for ending the switching operation interruption phase if the power supply voltage of the item of equipment is greater than a voltage threshold value. The item of equipment powered by the module comprises a capacitive element able to store energy from the module during the switching operation phase and to release the energy stored between the output terminals of the power supply module when it receives an activation signal.

[Object] To provide a display apparatus capable of obtaining excellent heat radiation performance of a light source while ensuring positional accuracy of the light source.

[Solving Means] A display apparatus according to an embodiment of the present technology includes a light guide portion, a casing, a projection portion, a heat source, and a heat-transfer member. The light guide portion is disposed in front of eyes of a user. The casing is fixed to the light guide portion. The projection portion is housed in the casing and is configured to be capable of projecting an image to the light guide portion. The heat-transfer member includes a first end and a second end, the first end being connected to the heat source, the second end being connected to an inner surface of the casing, and is configured to be deformable.

A display device according to an exemplary embodiment includes: a first display unit having a polygon shape for displaying an image; and a plurality of second display units displaying an image and respectively disposed adjacent to respective sides of the polygon of the first display unit. The plurality of second display units may be bent based on the respective sides such that the first display unit and the plurality of second display units form a three-dimensional shape.

Systems, methods, and media for projecting light to indicate a device status are provided. In accordance with some implementations of the disclosed subject matter, systems for projecting light to indicate a device status are provided, the systems comprising: a hardware processor that: determines a light status; determines whether to turn a light source on; selects a light format corresponding to the light status; projects light of a light source according to the light format; and determines whether to turn the light source off.
