ABSTRACT:

A gas-timing control method for depositing metal oxynitride and transition metal oxynitride (Mx(ON)y) films on glass and flexible substrates using reactive radio frequency magnetron sputtering, without substrate heating. A system includes a sputtering chamber, substrates, targets, three mass flow controllers controlled respective flow rates of argon, nitrogen and oxygen gases alternately and intermittently into the sputtering chamber, and a radio frequency generator with 13.56 MHz which irradiated in the sputtering chamber to decompose sputtering gases. The flow rate ratio of oxygen+nitrogen/argon is at least 0.02, the flow rate ratio of oxygen/nitrogen is at least 0.01, and the sequence timing of argon, nitrogen and oxygen gases alternately or mixed into the sputtering chamber at least 1 sec.

ABSTRACT:

The sequential stimulator the treatment of dysphagic patients comprises a unit which is capable of detecting a swallowing signal from the glossal or temporalis muscle SEMG. When a swallowing signal is recognized, a trigger signal is sent to the stimulation generation unit to release a high voltage stimuli sequentially to the suprahyoid muscles or the masseter muscles and the pharyngeal muscles in order to assist in the elevation of the larynx. This enables the pharyngeal lumen to open more widely so that food can pass through the patient’s pharynx and into the oesophagus more easily during swallowing. Thus the sequential stimulator is a device for assisting swallowing in patients with dysphagia due to a variety of causes, for instance, brain injury, cerebrovascular accident, injury of the cervical nerves, muscles weakness, or old age. The stimulator is operative only when the patient attempts to swallow and provides a physiologic stimulus and provides a means of immediate relief of the swallowing difficulty. However, the device is also useful for physical therapy whereby the muscles under the chin, the masseter muscles and the pharyngeal muscles can be reeducated to contract in the normal coordinated sequence.

ABSTRACT:

Optical touch switches are implemented based on the use of light total internal reflection and light scattering concepts. The optical touch switch basically consists of a light source, a light guide, a photodetector, and an electronic controller. The fingertip touching on the touching surface of the optical touch switch leads to the change in electrical current produced by the photodetector. As a result, the electronic control box senses this change of electrical current and allows the electrical load to stay at the desired state. Key advantages include ease of implementation, prevention of the light beam incident directly on the user’s eyes, and ability to accept both strong and weak mechanical forces from users.
