Abstract: A projection apparatus includes a casing, a motherboard, a power board, a light source, and a projection lens. The motherboard includes a host circuit board, a light valve, and a CPU, and is contained inside the casing. The light valve and the CPU are on the host circuit board. The power board includes a power circuit board and an AC/DC power module. The power circuit board is contained inside the casing, and the AC/DC power module is on the power circuit board. The light source is used to produce an illuminating beam. The light valve is used to transform the illuminating beam into an image beam. The projection lens is used to transform the image beam into a projecting beam. The power circuit board is parallel to the host circuit board. An optical axis of the projection lens is perpendicular to the host circuit board and power circuit board.

Abstract: An illumination system for a projection apparatus includes a light source module, an integrating rod and an optical detecting module. The light source module is capable of emitting an illuminating light beam. The integrating rod has a light entrance surface facing toward the light source module. The optical detecting module includes a light guiding device and an optical detecting device. The light guiding device has a first end surface and a second end surface. The first end surface is farther away from the light entrance surface of the integrating rod than the second end surface. The optical detecting device is disposed adjacent to the first end surface of the light guiding device and electrically connected to the light source module. The light source module is capable of adjusting intensity of the illuminating light beam according to randomly emitted light detected by the optical detecting device.

Abstract: An inner type tracheostomy tube has an outer tube and an inner cannula. The outer tube has an airway tube, an inflatable cuff and an inflating tube. The inner cannula is connected to the outer tube and has an inner tube, a disk segment, a connecting mount and a connector. The connecting mount is soft and bendable, is securely mounted around the disk segment and has a bottom end, a top end and a flange coat. The bottom end is securely mounted around the disk segment and has an inner surface and an air gap formed between the inner surface of the bottom end of the connecting mount and the disk segment. The connector is securely mounted around the top end of the connecting mount and has a bottom end and a flange formed around the bottom end of the connector and enclosed by the flange coat.

Abstract: An inner type tracheostomy tube has an outer tube and an inner cannula. The outer tube has an airway tube, an inflatable cuff, an inflating tube, a neck mount and a holding mount. The neck mount is mounted around the airway tube. The holding mount is formed on the neck mount around the airway tube and has a holding ring and two holding arms. The holding ring is formed on the neck mount. The holding arms are formed on the holding ring and protrude from the holding ring and each has a holding recess. The inner cannula is connected to the outer tube and has an inner tube, a disk segment and two locking tabs. The disk segment is formed on the inner tube. The locking tabs are formed on the disk segment, are respectively connected to the holding arms and each has a locking portion and a pressing button.

Abstract: An isolation valve for a closed suction device has a body and a valve. The body has a communicating channel, a patient end connector, a breathing circuit connector and a suction tube connector. The communicating channel has a chamber and an opening. The patient end connector, the breathing circuit connector and the suction tube connector are radially formed on and protrude from the external surface of the communicating channel and communicate with the chamber of the communicating channel. The valve is rotatably connected to the body and has an isolation pipe and a control button. The isolation pipe is rotatably mounted in the chamber of the communicating channel via the opening and has a communicating hole, an inlet hole and a sucking hole.

Abstract: Device and method capable of dynamically displaying digital images by coordinate conversion on a virtual plane are provided. The device includes a display unit, a storage unit, and a processing unit. The display unit includes a screen. The storage unit stores a digital image. The processing unit establishes a virtual plane including a display region corresponding to the screen of the display unit, projects the digital image on the virtual plane to form an image region, and decides a moving trace of the image region on the virtual plane. When the image region and the display region overlap, the processing unit calculates the overlap and displays a corresponding part of the digital image by reading from the storage unit on a corresponding part of the screen.
