The display device may include a display unit and a support unit. The display unit is used for displaying patient-end parameter information. The support unit comprises an adapter cover and a rotating unit connected onto the adapter cover. The display unit is fastened and connected onto the adapter cover in a way that allows rotation relative to the rotating unit. The monitor comprises: a master control unit and the display unit, where the master control unit is connected to a patient end via at least one cable, and the display unit is detachably connected to the master control unit. With the implementation of the monitor, the display device thereof, and the monitoring system, the display unit rotates and switches while the position of the connecting cable of the master control unit remains unchanged; corresponding marker display areas and alarm light display areas are lit up after rotating and switching in order to take into consideration habits of a user.

A quick release connector is provided that uses a plurality of the ball bearings to engage shaft of a releasable member. The use of multiple ball bearings along different faces of a shaft of a releasable member minimizes vibrations and provides an improved quick release connector adapted for use with microphones, boom arms, ball joints and similar structures used with sound recording or photography equipment.
摘要:
An events capturing apparatus for assisting a user to capture events comprising a support arm that includes a proximal end configured to removably receive a sound capturing device and a distal end configured to removably receive an image capturing device, and a handle coupled to the proximal end of the support arm and shaped to be held by the user. In some embodiments, the image capturing device is a smart-phone camera and the sound capturing device is a microphone.
摘要:
Embodiments of the invention provide a base assembly for supporting a free standing structure such as a tent. The base assembly is configurable such that a base can be positioned in a generally horizontal orientation to support and stabilize a stationary structure. In some cases the base can be positioned in a generally vertical orientation to allow the base assembly to roll along a support surface, thus providing a ready and easily configurable manner of transporting the base assembly and any structure attached thereto.
摘要:
A stand for adjustable display comprising: a holder configured to support an item to be displayed on the stand, a bottom edge of the holder configured to contact a surface on which the stand is placed; and an adjustable support configured to be attached to the holder, the adjustable support comprising a supporting leg having a first end configured to engage the holder pivotably about a first axis and a second end configured to contact the surface on which the stand is placed; and an adjusting bar having a first end configured to engage the holder pivotably about a second axis and a second end configured to slidably engage the supporting leg and to pivotably engage the supporting leg about a third axis; wherein the supporting leg comprises a locking mechanism configured to lock the stand in a stationary position between and including a minimum raised position and a maximum raised position such that the second end of the adjusting bar remains stationary on the supporting leg when raising of a top edge of the holder is stopped.
