3024 results about "Human power" patented technology

Human power is work or energy that is produced from the human body. It can also refer to the power (rate of work per time) of a human. Power comes primarily from muscles, but body heat is also used to do work like warming shelters, food, or other humans.

Method for monitoring and measuring full section of tunnel through three-dimensional laser

The invention relates to a method for monitoring and measuring a full section of a tunnel through three-dimensional laser, and belongs to the field of tunnel engineering construction monitoring. The method comprises the following steps of: arranging target points in a tunnel to be measured according to a requirement; determining whether to adopt one-station scan or multi-station scan according to the monitoring length of the tunnel; erecting an instrument at a proper position and scanning the full section of the tunnel; after the scan is finished, importing data into a computer; registering point cloud data acquired through the scan to generate a three-dimensional model by applying three-dimensional data processing software; and generating a comparison model by combining a previous three-dimensional model for the same tunnel at different time, and selecting a specific section and characteristic points to generate a variation analysis chart and a variation analysis sheet for a corresponding position. By the method, the full section of the tunnel is monitored in real time, the speed and accuracy of monitoring and measuring work are improved, manpower and material resources are saved, the speed and quality for monitoring and measuring the tunnel are improved, and reliable guarantee is provided for tunnel engineering construction.

Human-powered dry powder inhaler and dry powder inhaler compositions

In one embodiment, a human-powered dry powder inhaler comprises a human-powered compressible component operable to discharge an air pulse at an outlet at a pressure of about 1-40 psi; an inflatable reservoir operable to receive an air pulse discharged from the human-powered compressible component to provide an aerosol of a dry powder pharmaceutical formulation in the reservoir, the reservoir including an outlet valve; and a receiving mask in communication with the outlet valve and operable to receive an aerosol of dry powder from the reservoir and to deliver the aerosol to at least a mouth or nose of a patient. In another embodiment, the inhaler comprises a human-powered compressible component operable to discharge an air pulse at an outlet of a polymeric pressure release valve at a pressure of about 1-40 psi; and a receiving mask in communication with the outlet of the compressible component and operable to deliver an aerosol of dry powder to at least a mouth or nose of a patient. Methods for delivery of a dry powder pharmaceutical formulation to a patient are conducted in the absence of electrical power and circuitry and pre-pressurized propellant gas. Suitable dry powder pharmaceutical formulations may include myo-inositol and/or maltodextrin as a carrier and active ingredients such as vaccines or siRNA.
