Abstract: A display may have an array of pixels. Display driver circuitry may supply data and control signals to the pixels. Each pixel may have seven transistors, a capacitor, and a light-emitting diode such as an organic light-emitting diode. The seven transistors may receive control signals using horizontal control lines. Each pixel may have first and second emission enable transistors that are coupled in series with a drive transistor and the light-emitting diode of that pixel. The first and second emission enable transistors may be coupled to a common control line or may be separately controlled so that on-bias stress can be effectively applied to the drive transistor. The display driver circuitry may have gate driver circuits that provide different gate line signals to different rows of pixels within the display. Different rows may also have different gate driver strengths and different supplemental gate line loading structures.

Abstract: A candle lantern equally suitable for indoor and outdoor use, and which further doubles as a decorative candle holder, comprising a body made from a tube of translucent material, for example glass or plastic, and two interchangeable candle-holding cups/heat shields mounted in the upper and lower ends of the tube, respectively, by set screws extending through holes in the tube. A base comprising a set of wire legs is preferably provided at the lower end of the tube, secured to the tube by the lower set of set screws, while a retractable bail handle and optional rain shield are provided in the upper end of the tube and secured to the upper set screw structure. In a preferred form the candle-holding cups include both blind apertures for receiving the set screws against the outer surface of the cup, and a set of holes for allowing the set screws through the cup to engage undersized candles.

Abstract: A portable emergency breathing apparatus provides both a source of breathing gas and a source of light to a person confronted by an emergency situation. Breathing gas from a supply container is distributed through a mouthpiece to the user. Further, a flashlight is removably affixed to the breathing gas supply container for use by the user. The apparatus is stored within a storage container adapted for convenient storage and transition to use of the emergency apparatus. The storage container comprises a storage body and cap member. The mouthpiece of the breathing apparatus is secured proximate the interior surface of the capping member. In this manner, access to the capping member provides for immediate access to the mouthpiece and facilitates removal of the emergency equipment from the storage container.

Abstract: Golf club swing training apparatus includes an upwardly extending support consisting of a fixed lower part and a forwardly-tiltable upper part, and a back holding member, adjustable in length and a waist holding member which members are each rotatably mounted on the upper part at a mid portion thereof for turning motion about the axis of said upper part. A strap is provided at the ends of each holding member for attaching the back holding member to the upper part of the golfer's arms and the waist holding member to the golfer's waist.
