Abstract: A wearable apparatus and a photoplethysmograph (PPG) sensor unit are provided. The wearable apparatus includes a wearable holder and a physiological information measurement module configured to the wearable holder. The physiological information measurement module includes a circuit board, an electrocardiograph (ECG) sensor unit and a PPG sensor unit. The PPG sensor unit is disposed on the circuit board and adapted to be used in conjunction with the ECG sensor unit electrically connected to a first pad and a second pad on the circuit board. The PPG sensor unit includes a grid having a plurality of accommodating spaces, a lighting element arranged in one of the accommodating spaces, and a photo sensor arranged in another accommodating space. The grid includes an inner conductive contact portion exposed from the wearable holder, facing an inner side of the wearable holder and electrically connected to the second pad.

Abstract: A gas sensor includes a base, an insulating layer, two sensing electrodes, a heating layer, a gas-sensing material, and an exciting light source. A thru-hole is formed on the base, the insulating layer is disposed on the base to cover the thru-hole, and a portion of the insulating layer corresponding to the thru-hole is defined as an element area. Each sensing electrode disposed on the insulating layer has a sensing segment disposed on the element area and a sensing pad disposed outside the element area. The heating layer disposed on the insulating layer has a heating segment disposed on the element area and two heating pads disposed outside the element area. The gas-sensing material is disposed on the element area and covers the sensing segments and the heating segment. The exciting light source is arranged in the thru-hole and is configured to emit light toward the gas-sensing material.

Abstract: A lead frame assembly includes a surrounding frame and a plurality of lead frame sets arranged in a matrix. Each lead frame set includes spaced-apart first and second lead frames and a connecting structure interconnecting one of the lead frame sets to an adjacent lead frame set. Each lead frame set is further connected to the surrounding frame through the connecting structure thereof. A plurality of insulated bars are spacedly formed on a lead frame panel. Each insulated bar covers a corresponding row of the lead frame sets and exposes bottom surfaces of the first and second lead frames. Each insulated bar further covers portions of the surrounding frame that are adjacent to two opposite outermost ones of the lead frame sets.
