The present invention relates to Caffeine Orange, a novel aqueous-phase fluorescence turn-on sensor for caffeine that is structurally based on a BODIPY-scaffold. The present invention further provides for methods of detecting and measuring caffeine in aqueous media. A change in the intensity or visible color of the fluorescence is detectable by either a fluorimeter or by the naked eye. The methods disclosed herein provide for the utilization of a reverse-phase SPE column, optionally as a component in a syringe or a microfluidics-based automation detection system. The invention further provides for the solid phase extraction of an analyte such as caffeine from a liquid medium, the extraction occurring on a microfluidic disc.

||PCT/SG2014/000160||HEPTAGON MICRO OPTICS PTE. LTD.||RIEL, Peter|
One or more channels are provided in the surface of a conductive layer of a PCB substrate in an area on which a component is to be placed. The channels can help reduce or prevent shifting of the component during reflow soldering through surface tension/capillary forces of the solder paste material in the channels. Such channels also can be used, for example, by an image processing system to facilitate accurate positioning and/or alignment of the component. The image processing system can use the location of the channels alone, or in combination with other features such as a solder mask or other alignment marks, to position and/or align the component with high accuracy.

||PCT/SG2014/000176||FCI CONNECTORS SINGAPORE PTE LTD||SASAME, Naotaka|
An electrical connector comprises a housing, contact elements and locking members attached to the housing. The housing has a front end, a back end, a top side, a bottom side and a cavity between the top side and the bottom side. The cavity is to partially receive a circuit board therein. Each contact element is insertable into the housing along a direction from the bottom side towards the top side. Each locking member is insertable into the housing along a direction from the bottom side towards the top side. The upper and lower contact arms and the lock arm are resiliently deflectable away from the cavity to allow insertion of the circuit board into the cavity, and spring back when the circuit board is inserted into the cavity to make electrical connection to the circuit board and to lock the circuit board in the housing.
