The electronic device of the present disclosure has a mounting section, a voltage determiner, and an attach-detach detector. The mounting section accepts a removable, externally-connected device and connects to a data line into which a unit signal having a data period for transmitting a data signal and a detection period for transmitting a detection signal is fed from the externally-connected device. The voltage determiner determines an electric potential of the data line so as to have a first logical value when the externally-connected device is detached from the mounting section. The attach-detach detector detects whether the externally-connected device is mounted on, or detached from the mounting section by detecting the detection signal of the first logical value determined by the voltage determiner or a second logical value.

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).

The present invention relates to an underwater photographic lighting device which comprises: a flashlight body fully sealed by a seal, the interior of the flashlight body is provided with waterproof through holes, the flashlight body is respectively connected to a lamp head and a flashlight via conductive connecting cables, the lamp head is sealed by a seal, and connecting parts can be respectively dismounted from the flashlight body; and a power supply component sealed by a seal and connected to the flashlight body. Every part of the underwater photographic lighting device of the present invention is sealed, so the waterproof function is better; and each part is independent, and therefore can be optionally replaced and maintained. The battery module can be replaced and upgraded according to future need, and can be independently charged, so that the life cycle of the whole device is extended. When a beam head is used for photographing, a reflection cup and a condensing lens that are added on the beam head can increase light efficiency, so that a better photographing and recording effect can be achieved. In addition, since the device can be connected to a camera or a camcorder without a grip, a clamp or other parts, the device is convenient, light in weight and practical.

An illumination apparatus which is capable of suppressing a mismatch between color temperature information for each of a plurality of light emitting units that illuminate a subject with light. Whether an optical accessory for toning or adjusting a light distribution angle is attached is detected for each of the plurality of light emitting units. The color temperature information indicative of a color temperature in a light emission when the plurality of light emitting units are caused to emit the light is decided according to light emission information indicative of a light emission state in each of the plurality of light emitting units and a detection result.

A system for electronic patient care includes a hub. The hub is configured to monitor a patient-care device. The sandbox may be configured to control access to at least one of a hardware resource and a software resource. 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 shoe apparatus includes an engagement portion with an accessory shoe apparatus included in an electronic apparatus, a plurality of connection terminals, where a first direction is an attachment direction to the accessory shoe apparatus, which are arranged in a second direction orthogonal to the first direction, and located on a front side of the engagement portion in the attachment direction, and a connector that includes protrusion portions that protrude in a third direction orthogonal to the first and second directions on both outer sides of the plurality of connection terminals in the second direction. The protrusion portion includes a slope portion on a side that does not face the plurality of connection terminals such that a width in the second direction at a position of a tip in the third direction is narrower than a width at a position away from the tip.

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.

In some aspects, camera systems can include a camera enclosure, a lens disposed in or along the camera enclosure along an optical axis of the camera system, and an optical accessory attached to camera enclosure, where the optical accessory is attached using a magnetic retention force that is provided by at least one magnetic element.

In a first communication mode, a control unit controls a signal level of one contact based on a first command received from an imaging apparatus via another contact and a signal level indicated by an accessory device via yet another contact. In a second communication mode, the control unit receives a second command indicating the second communication mode and data via another contact. After the reception, the control unit transmits the data via still another contact. The control unit controls communication in the second communication mode based on the signal level of the one contact and the second command.
