A carbon credit is a generic term for any tradable certificate or permit representing the right to emit one ton of carbon dioxide or the mass of another greenhouse gas with a carbon dioxide equivalent (tCO2e) equivalent to one ton of carbon dioxide.

Carbon credits and carbon markets are a component of national and international attempts to mitigate the growth in concentrations of greenhouse gases (GHGs). One carbon credit is equal to one ton of carbon dioxide, or in some markets, carbon dioxide equivalent gases. Carbon trading is an application of an emissions trading approach. Greenhouse gas emissions are capped and then markets are used to allocate the emissions among the group of regulated sources.

Carbon credits can be generated by any process that conforms to ISO 14064-66 standards. Once generated, carbon credits can be stored in a distributed, Cloud-based ledger. The ledger entries can serve as a registry for carbon credits as well as the data source for an Internet-enabled trading system or financial exchange that allows the carbon credits to be sold and bought as part of the same system. The distributed ledger can provide records that combine the details of the carbon credits' origin, transaction history, and financial instructions associated with trading of the carbon credits via a distributed ledger system.

Provided is an apparatus and method for calibrating a channel in a radio communication system using multiple antennas. A base station apparatus for the radio communication system includes a channel estimator and a calculator. The channel estimator receives a UL sounding signal to estimate a first UL CSI and receives a UL sounding signal weighted with a DL CSI to estimate a second UL CSI. The calculator calculates calibration values for the respective antenna pairs using the first UL CSI and the second UL CSI. Information necessary for channel calibration is transmitted and received in an analog format. Accordingly, it is possible to minimize the waste of resource and time necessary for channel calibration.

Assemblies in accordance with the invention can lead to an exceptionally easy to use, safe, and convenient system and method of applying a fixed dosage of chemicals to which a user might wish to avoid contact, such as parasiticides. In the present invention, a fluid, such as a pesticide or parasiticide, glue, solvent, lubricant, medicament and the like is loaded into a fluid reservoir and the reservoir sealed. The reservoir can be attached to a cap-applicator structure which is in an inactive configuration. In the inactive configuration, a piercing tip remains poised over the reservoir in an inactive configuration without forming an opening in the reservoir. The cap-applicator can have a sharp intsernal piercing tip capable of piercing the reservoir when the assembly is converted into an active configuration. This will allow the user to dispense the liquid out of the reservoir through the applicator.

A mascara brush head includes bristles made from shape memory polymer (SMP) filaments or fibers. The shape memory polymer filaments are selected to exhibit a first shape during assembly of the brush, and a second shape after exposure to an external stimulus in the form of heat or other energy. The brush head is initially assembled, i.e., lengths of SMP filaments are placed between wire segments and the wire segments are then twisted about each other to form a twisted wire core. The core grips the filament lengths medially of their outer ends, usually substantially at their midpoints, so as to clamp them. The first shape can be straight to facilitate assembly of the fibers in the wire core. The second shape, after assembly in the core and after being subjected to the external stimulus, can be any bristle shape suitable for enhancing the function of the brush, e.g., kinked, wavy or coiled. The brush head may be comprised solely of SMP filaments, or may be a blend of SMP filaments and any other suitable filament (e.g., nylon, natural plant or animal fibers, etc.).

The present invention is a hybrid system for generating power from hydrocarbon and alcohol fuels using a two-stage process to achieve high overall energy conversion efficiency. The first stage is a reformer and fuel cell subsystem that uses an internal combustion engine operated at an air/fuel ratio richer than stoichiometric as a partial oxidation reformer for commonly available liquid or gaseous hydrocarbon or alcohol fuels. The engine produces shaft power and a product gas mixture containing hydrogen, carbon monoxide, and traces of light hydrocarbons that is used as fuel in fuel cells to generate electric power. The second stage is a heat engine subsystem that captures heat from the reformer and fuel cell subsystem, and produces additional shaft power. In addition to efficiency, advantages include adaptability to a variety of fuels, quick system startup with immediate shaft power availability, and low emission of pollutantants.

Wasteful use of radio resources is minimized in a packet transmission system which performs retransmission control at a higher layer. When transmission of a segment has failed at a lower layer and, for example, when the number of lower-layer retransmit requests from an error detection unit at the lower layer has exceeded a predetermined threshold, any other segment remaining to be transmitted in a packet of which the failed segment forms a part is discarded and, at the same time, a retransmit request is sent to a retransmission control unit at the higher layer.
