Abstract: Scanners with wakeup systems are disclosed herein. An example scanner assembly includes a wakeup system having an infrared (IR) transmitter configured to project IR illumination through a window of the scanner and an IR receiver. The IR receiver has a second field-of-view (FOV) directed through the window that overlaps a first FOV of an imaging assembly of the scanner by at least 50% at the window and has a second central axis that is non-perpendicular to the window such that the second central axis is tilted downward from horizontal with the scanner assembly positioned in a vertical first configuration where the window is in a generally upright orientation. A controller of the scanner is configured to activate an illumination system when the IR receiver detects IR illumination reflected from an object in the second FOV of the IR receiver.

Abstract: A bracket that can be used to run electrical wires, mostly low voltage, during construction when devices or finished structures are not yet installed. The bracket can be mounted to in-wall, in-ceiling and other structures to provide a finished location to terminate caballing before finishes are installed. Cable can be temporarily affixed to the bracket to prevent unwanted movement and plugged during trim-out if not needed.

Abstract: A method of well rehabilitation using CO2 comprises a more effective distribution of effective CO2 energy throughout an entire well structure including all parts of a producing interval of a well and surrounding formation. The CO2 phase changes are controlled during CO2 injection to cause surging agitation within a well bore and surrounding formation and allow CO2 energy to reach all areas of the well, and the CO2 energy utilized includes at least one of chemical energy, thermal energy and mechanical energy.

Abstract: The invention relates to a method of well rehabilitation using CO2. The improvement comprises providing a more effective distribution of effective energy throughout the entire well structure including all parts of the producing interval of the well and surrounding formation and distributing energy throughout the entire well structure. The improved method is obtained by controlling CO2 phase changes during CO2 injection to cause surging agitation within the well bore and surrounding formation and allowing CO2, mechanical energy and optionally chemical energy to reach substantially all area of the well.

Abstract: Systems and methods are provided for processing electronic payment from a portable device that is associated with a user to a payment network via a merchant device and a gateway. The gateway can be notified when the user is in a merchant's premises. For example, the gateway can receive a token associated with the user's portable device and then use this token to retrieve the user's profile. The gateway can also receive a payment request initiated by the user, and in response, authenticate the user based on the user's profile, process the payment request, and notify the merchant if the payment is approved. During the payment process, the user advantageously does not need to share his or her personal or financial information at the point of sale in the merchant's premises.
