Abstract:
A system for monitoring a building having one or more microphones coupled to a telephone includes a detector configured to detect a triggering event within the building and transmit an activating signal when the triggering event is detected, and a control module configured to receive the activating signal from the detector. The control module is programmed to activate at least one of the one or more microphones to monitor sound when the activating signal is received.
Abstract:
A system for providing a joint for connecting a first object and a second object includes a data acquisition device configured to acquire joint parameter data regarding the first object and the second object, and a controller coupled to the data acquisition device and configured to provide joint design data regarding a design of the joint based on the joint parameter data.
Abstract:
The embodiments disclosed herein relate to construction systems, assemblies, and methods. The construction systems can include concrete dispensing assemblies. The concrete dispensing assemblies can be configured to dispense a plurality of discrete units. The concrete dispensing assemblies can also be configured to simultaneously dispense two or more concrete mixtures. One or more dispensing parameter may be controllable, for example, by a computer control system. Additives and/or curing agents may also be used. Exemplary curing agents include carbon dioxide containing materials.
Abstract:
A traceable cement mixture includes a volume of cementitious material, a plurality of taggants disposed within the volume of cementitious material according to a taggant mix ratio that is specified based on a quality of the cementitious material, and a volume of an additional material mixed with the volume of cementitious material according an additional material mix ratio.
Abstract:
A method of controlling a Casimir-effect device includes applying a voltage to a field-effect gate of the Casimir-effect device. The Casimir-effect device includes a conducting material and a semiconductor. The conducting material and semiconductor are separated by a gap to form the field-effect gate over at least a portion of the semiconductor facing the gap. The method further includes altering, in response to the applied voltage, a density of free charge carriers in the portion of the semiconductor facing the gap to control a nanoscale Casimir force between the conducting material and the portion of the semiconductor facing the gap.
