Abstract: Isolated peptides comprising at least one epitope, such as a T or B cell epitope, of the Group II proteine allergen from Dermatophagoides, Der p II, are disclosed. Also disclosed are therapeutic compositions containing one or more such peptides, and therapeutic methods of using such peptides. Also disclosed are diagnostic compositions containg one or more such peptides, and dianostic methods of using such peptides.

Abstract: Isolated allergens of Dermatophagoides (house dust mites) particularly of the species and Dermatophagoides pteronyssinus, which are protein allergens or peptides which include at least one epitope of the protein allergen. In addition, the or peptides encoded by the isolated DNA, their use as diagnostic and therapeutic reagents and methods of diagnosing and treating sensitivity to house dust mite allergens.

Abstract: Recombinant DNA expression vectors or cloning vehicles capable of expressing a polypeptide displaying the antigenicity of an allergen of house dust mites of the genus Dermatophagoides. A synthetic protein or polypeptide displaying antigenicity of all or a portion of an allergen of house dust mites of the genus Dermatophagoides. Methods of diagnosing and treating such allergies.

Abstract: Isolated DNA encoding allergens of Dermatophagoides (house dust mites) particularly of the species Dermatophagoides farinae and Dermatophagiodes pteronyssinus, which are protein allergens or peptides which include at least one epitope of the protein allergen. In particular, DNA encoding two major D. farinae allergens, Der f I and Der f II and DNA encoding a D. pteronyssinus allergen, Der p II. In addition, the proteins or peptides encoded by the isolated DNA, their use as diagnostic and therapeutic reagents and methods of diagnosing and treating sensitivity to house dust mite allergens.

Abstract: A magnetic tape drive dynamically adjusts a transport rate of tape (32) in accordance with a host data rate. The host data rate is assessed in relation to a data fill level of a buffer (116). A controller (130) of the drive compares the data fill level of the buffer with a buffer normalization value and generates an adjustment value for adjusting a signal indicative of the desired linear velocity of the tape. In one embodiment, the controller also dynamically changes the buffer normalization value to reflect e.g., historical performance of the host. In another embodiment the controller adjusts the transport rate when a head (100) is within a predetermined distance of a boundary point whereat the head must change tracks.

Abstract: A fine position closed loop servo system is disclosed for magnetic disk storage media having a plurality of data storage disks in which a first servo burst is contained on the surface of one of the data storage disks, the servo burst data being spaced at radial positions one-half track displaced from each of the odd-numbered concentric track centerlines and a second servo burst signal is contained on the surface of another of the data storage disks, the second servo burst signal being recorded at radial positions one-half track displaced from the even-numbered concentric track centerlines. Both the first and second servo burst data are read simultaneously utilizing the data transducers associated with the surfaces of the respective data storage disks and the envelopes of each of the servo burst signals are simultaneously, separately detected.

Abstract: An active termination circuit for a computer interface for reducing line reflection of logic signals. A first and second resistor combination is permanently connected to a cable that couples a plurality of peripheral devices to one another. The other ends of the first and second resistors are connected through a switching device to a positive voltage supply line and to logic ground, respectively. That switching device may be a transistor. When termination of multiple devices is required, a plurality of resistor combinations is provided but on/off control of the switch is achieved by one control that is located remote from the termination circuit.
