A method and an apparatus are provided for using a capacitor chain to perform charge sharing and Anger logic to determine, for charge pulses arising from gamma-ray detection, a row position along an array of scintillation-based gamma-ray detectors. Further, high-pass filters configured at the ends of the capacitor chain perform pulse shaping to preserve timing information. To determine the column position for charge pulses, a two-stage summing amplifier configuration is used with weighting amplifiers controlling the relative gain of the second-stage amplifier with respect to respective columns in the array. Each detector element in the array is a silicon photomultiplier (e.g., Geiger-mode avalanched photodiodes biased above breakdown voltage). Position information can be generated by Anger logic on four outputs from the second-stage amplifiers. Energy and timing information can be generated as a sum of the four outputs from the second-stage amplifiers.

A parapet molding flashing installation system, for a foam molding to a building. The molding having an upper surface, and having a channel extending along the molding. The channel having an upper opening along the upper surface of the molding. An anchor insert extends in the channel and has an exposed face at the upper opening of the channel for attaching a flashing cap to the anchor insert to thereby secure the flashing cap to the anchor insert.
