The hub is further configured to identify the patient-care device and execute an application to monitor the patient-care device. The hub executes the application within the sandbox component such that the application accesses the at least one of the hardware resource and the software resource through the sandbox component. The hub may be further configured to control the patient-care device. The hub may be further configured to receive an identification from the patient-care device and download the application from a server associated with the identification. The hub may be further configured to receive an identification from the patient-care device and update the application from a server associated with the identification.

A system and method for synchronizing a remote lighting device to a camera using a hot shoe connection and an external device connected via the hot shoe connector. The external device receives TTL data and a synchronization signal from the camera via the hot shoe connector. The external device wirelessly communicates using a radio frequency transmitter an exposure compensation value from the external device to a remote lighting device. The external device also wirelessly communicates a synchronization signal and a TTL information to the remote lighting device for use in synchronizing the remote lighting device to image acquisition by the camera.

A portable selfie stick, including a multi-stage telescopic rod (1), and a bracket assembly (2) and a handle (3) respectively arranged at a head end and a tail end of the multi-stage telescopic rod. The portable selfie stick further includes a wireless charging device (4), the wireless charging device (4) includes a wireless charging coil (41) and an electromagnetic power converter arranged at the bracket assembly (2), a power line arranged in the multi-stage telescopic rod (1) in a penetrating manner, and a mobile power source (42) arranged in the handle (3); both ends of the power line are in electric connected with the mobile power source (42) and the electromagnetic power converter, respectively; and the electromagnetic power converter is electrically connected with the wireless charging coil (41).

An accessory shoe device capable of preventing fall-off of fastening screws, without increasing the number of component parts. An accessory shoe device is mounted on an exterior member of an electronic apparatus. A fastening screws fastens a holding member disposed inside the exterior member, the exterior member, a terminal member attached to the exterior member and having a terminal to be connected to the accessory, and an engaging member on which the accessory is mounted, in the mentioned order, from inside the exterior member. A flexible circuit board is disposed on a surface of the holding member opposite to a contact surface thereof in contact with the exterior member, and is electrically connected to the terminal. The flexible circuit board is formed with a slit having a predetermined shape, thereby being provided with a flexible portion for pressing down a head of the fastening screw.

A system and method is provided for affixing a first mobile device (e.g., a smartphone, etc.) having a camera feature to a stand (e.g., a tripod) having a motor, where a second mobile device (e.g., a tablet, etc.) is used to control at least the motor, thereby adjusting the first mobile device in relation to the stand. In another embodiment, the second mobile device is further used to control other features, such as shutter, flash, focus, etc. In a first embodiment, this is accomplished via a single wireless communication channel between the second mobile device and either the first mobile device or the stand and a second (e.g., wired or wireless) communication channel between the first mobile device and the stand. In a second embodiment, this is accomplished via a plurality of wireless communication channels between the second wireless device and the first mobile device and/or the stand.

An image projection device is disclosed having a body defining an aperture that includes a slide frame receiving slot that is transverse to the aperture and a magnifying lens positioned in alignment with the aperture at the front of the body. The image projection device can be attached to a mobile device and uses the camera flash of the mobile device to provide the light source to illuminate a slide transparency. The mobile device can identify a particular slide transparency through information encoded on the slide frame in order to coordinate audio or video output with the projected slide.

A low-glare fluorescent-powder LED light device includes a shell, a multi-frequency directional light source, a high-frequency directional light source, and an electrical control circuit. The shell has a surrounding wall, which defines a front opening and a rear opening and has an inner surface extending along a central axis. The multi-frequency directional light source, including at least one fluorescent-powder LED, is disposed at the inner surface of the shell. The high-frequency directional light source, including a plurality of high-frequency LEDs, is disposed at the inner surface of the shell such that the high-frequency LEDs are arranged in radial symmetry about the central axis. The electrical control circuit can drive the multi-frequency directional light source and/or the high-frequency directional light source. The central light beams emitting from the high-frequency LEDs do not reach the fluorescent-powder LED, so that the fluorescence interference of the fluorescent-powder LED can be avoided.

An optical device includes a clamp seat and a light tuning assembly. The clamp seat includes a base, a curved portion extending from the base, and a pressing portion extending from the curved portion. The light tuning assembly includes a support frame disposed at the base, an optical lens restrained by the support frame, and an adjusting member coordinating with the optical lens. In an application of the optical device, a user may clamp a multimedia mobile communication device by the base and the pressing portion to allow the optical lens to align with a light projecting assembly of the multimedia mobile communication device. The adjusting member is rotated to adjust a distance between the optical lens and the light projecting assembly. Light from the light projecting assembly is then focused or dispersed through the optical lens to solve an issue of unadjustable light of a conventional solution.
