Abstract: This invention discloses a cyclic process for the production of astaxanthin rich biomass by cultivating Haematococcus algae. Modified nutrient medium containing 4 nitrogen sources is used for culturing the algae. Green motile cells produced are converted into dormant red cysts which are chilled and stressed for vigorous multiplication. Nutrients are added gradually and the initial germination is carried out without carbon dioxide sparging. The dilution stage is also effected in the absence of carbon dioxide. The stressed red cysts are regerminated and the cycle repeated to produce a biomass enriched with astaxanthin.

Abstract: A portable communication device uses a first electrostatic antenna element and a second electrostatic antenna element and circuitry which is coupled to the first antenna element and to the second antenna element and which derives operating power from an electrostatic field in the vicinity of the first and second antenna elements. The electrostatic field may be provided by an array of exciter elements containing both horizontal and vertical exciter elements so that at some point as a communication device is moved across the exciter antenna array, the device will have sufficient power coupled to it to power up and become operational.

Abstract: A radio frequency identification tag system (10) utilizes a radio frequency identification tag (16) that includes stored information. The tag includes an antenna element (28) and a common electrode (26), the common electrode being coupled to ground (70). The antenna element electrostatically receives an exciter signal (30) from a proximately-located exciter (12). Upon receiving the exciter signal, the tag becomes energized, thereby causing it to generate a read signal (32) based on the stored information. The antenna element then electrostatically sends the read signal to a proximately-located reader (14), which detects the stored information. Both energy and data are capacitively coupled by virtue of the unbalanced nature of the network, thus resulting in decreased coupled impedance.

Abstract: A radio frequency identification tag exciter/reader (10) is arranged for operation in association with an article transport device (100). The radio frequency identification tag exciter/reader (10) includes a canopy assembly (12) into which an exciter antenna (22) and a reader antenna (24) are positioned. A base station (26) is further provided and is coupled to the exciter antenna (22) and the reader antenna (24). The base station (26) provides an excitation signal (36) and receives a read signal (38). The base station further communicates with a system element (34). A hand held radio frequency identification tag exciter/reader (900) includes a hand holdable housing (912) including an exciter antenna (922) and a reader antenna (924). The housing is coupled to a portable base station (926). The base station (926) provides an excitation signal (936) and receives a read signal (938). The base station further communicates with a system element (934) via radio signals (932, 933).

Abstract: Method and radio station for transmitting information via a GSM mobile radio network. When information, in particular packetized data, is being transmitted via a GSM mobile radio network, the context definition for the radio interface between the mobile station and the base station takes place at a different time from the setting up of the physical traffic relationships, and thus uses the radio resources for this physical traffic relationship more efficiently.
