Abstract: Methods, systems, and devices for a programmable finite field generator for memory are described. In some cases, a system (e.g., a memory system, a host system) may store coefficient values indicating Galois Field multipliers in an array of configuration registers associated with a finite field generator. To update a set of values stored in a set of registers associated with the finite field generator, the system may perform a set of Galois Field multiplication operations according to Galois Field multipliers indicated by the coefficient values stored in the array of configuration registers. The system may perform at least one Galois Field summation operation on one or more of the multiplied values to generate an updated value. Then, the system may store the updated value in a first register from the set of registers, and shift the set of values along the remaining set of registers.

The product can be provided in a kit of two or more products, such as to release different doses of the nicotinic agonist.

Abstract: A spectrometer includes a light source that emits a beam into a sample volume comprising an absorbing medium. Thereafter, at least one detector detects at least a portion of the beam emitted by the light source. It is later determined, based on the detected at least a portion of the beam and by a controller, that a position and/or an angle of the beam should be changed. The beam emitted by the light source is then actively steered by an actuation element under control of the controller. In addition, a concentration of the absorbing media can be quantified or otherwise calculated (using the controller or optionally a different processor that can be local or remote). The actuation element(s) can be coupled to one or more of the light source, a detector or detectors, and a reflector or reflectors intermediate the light source and the detector(s).
