Recently, smartphones have been used as remote controllers for home appliances through connectivity of mobile telecom network or Wi-Fi. To control several home appliances in a room, a mechanism is required for a smartphone to correctly select the target appliance. Through the built-in electronic compass function in the smartphone, we propose a scheme called Point-and-Control (PnC) that allows a...

Twin Block appliance has been widely used for the treatment of Class II malocclusions in growing subjects, due to its versatility and its highly compliance nature. There are certain clinical indications where functional appliances can be used successfully in Class II malocclusion as in a growing patient. In using these appliances, the main concern is compliance of patients. This appliance simpl...

sleep apnea, and particularly obstructive sleep apnea, is a common disorder that is characterized by a repetitive, partial or complete cessation of air flow, associated with oxyhemoglobin desaturation and an increased effort to breath. in recent years, orthodontists have been interested and involved in the management of this disorder since it has been shown that oral appliance therapy can be an...

The Pendulum appliance is one of the most terrific and useful appliances for the treatment of Class II malocclusions in non-compliant patients. As reported by Hilgers, the appliance has its anterior anchorage based on a Nance button which can be connected to the first premolars (or the first deciduous molars) and to the second bicuspids (or second deciduous molars) using bonded occlusal rests. ...

In this thesis, I designed and implemented the run-time operating system (RTOS) for the MASC system. The Modular Appliance Super Computer (MASC) system proposes a novel solution to the problem of efficient information appliance (IA) design. To add functionality to a MASC IA, one simply inserts inexpensive, credit card-sized computer and peripheral cards into a standard backplane embedded in the...

The aim of this study is to present a new upper molar distalization appliance called Cise distalizer designed as intraoral device supported with orthodontic mini screw for upper permanent molar distalization. The new appliance consists of eight main components. In order to understand the optimum force level, the appliance under static loading is tested by using strain gage measurement technique...

niosomes are non-ionic surfactant vesicles that have potential applications in the delivery of hydrophilic and hydrophobic drugs. the topical form of n-acetyl glucosamine (nag) recently has been considered in the treatment of hyperpigmentation disorders due to its inhibitory effect on thyrosinase enzymes in melanocytes. to improve nag penetration into the skin we formulated the drug in niosomes...

pterygium is characterized by an elastic degeneration of the conjunctiva that extends across the limbos and invades the cornea. the recurrence rate is varied from 25-80% after primary closure to 6% with free conjunctival and iimbal grafts. several adjunctive therapies have been investigated for recurrent pte¬rygium. this article presents a 52-year-old athletic man who was seen for evaluation of...

The effect of the Twin Block functional orthodontic appliances is mostly dento-alveolar with small skeletal effect. There are certain clinical indications where functional appliances can be used successfully in class II malocclusion e.g. in a growing patient. The use of these appliances is greatly dependent on the patient's compliance and they simplify the fixed appliance phase. In this case, a...
