    Abstract: A moving coil actuator that moves in a rapid back-and-forth motion is constructed with a magnet assembly that concentrates the magnetic flux in a region of limited length and with a coiled electric conductor that includes two separated regions of densely wound coil, the assembly and conductor arranged such that only one of the coil regions resides in a concentrated flux region at either end of the actuator stroke. This is achieved with either a single region of concentrated flux or two spatially separated regions of concentrated flux. In either case, the force constant, i.e., the motor force generated in each coil per unit of current through the coil, is non-linear, with a maximal force at each end of the stroke and a minimal force at the stroke mid-point. The result is an efficient use of the electric current and relatively small amounts of materials of construction, and accordingly less weight for the actuator to carry during its travel and its changes of direction.

    Abstract: Methods and apparatuses associated with stepping down a high voltage in a high voltage switch. An additional transistor may be coupled to a switching transistor, and the additional transistor biased to a voltage level in between the high voltage to be switched and a switch reference voltage. When the switch is off, the high voltage may thus be spread across multiple devices to prevent a voltage from the gate to the drain to exceed a threshold associated with gate-aided breakdown of the drain-to-substrate channel-side pn-junction.

    Abstract: A multi-die memory package may have separate chip enable inputs for the respective memory dice. Individual chip enable inputs may be separated by other chip connections such as power and ground. The memory dice may include multiple chip enable inputs to allow easy wire bonding of the individual chip enable inputs to a die without requiring any jumpers within the package. Circuitry may be included so that undriven chip enable inputs are masked and driven chip enable inputs may be propagated to the memory die to enable memory accesses while a single chip enable input is only connected to the capacitance of a single bonding pad.

    Abstract: Provided herein are semi-synthetic glycopeptides having antibacterial activity. The semi-synthetic glycopeptides described herein are made by chemical modification of a glycopeptide by hydrolyzing the disaccharide moiety of the amino acid-4 of the parent glycopeptide in acidic medium to give the amino acid-4 monosaccharide; conversion of the monosaccharide to the amino-sugar derivative; acylation of the amino substituent on the amino acid-4 amino-substituted sugar moiety with certain acyl groups; conversion of the amide group in amino acid-3 to various acylamide, acylsulfonamide, acylsulfonylurea derivatives; aminomethylation with substituent containing sulfonamide or acylsulfonamide group on amino acid-7 through Mannich reaction; and conversion of the acid moiety on the macrocyclic ring to certain substituted amides. Also provided herein are pharmaceutical compositions comprising the semi-synthetic glycopeptides, and methods of use of the semi-synthetic glycopeptides for the treatment and/or prophylaxis of diseases, especially bacterial infections.
