Abstract: Systems and methods are provided to perform a vehicle function. A vehicle function command is detected and it is determined if an event moved is active. In response to a determination that the event mode is active, an event mode parameter is retrieved. Otherwise, in response to a determination that the event mode is not active, a normal mode parameter is retrieved. The vehicle function is performed based on the retrieved event mode parameter or normal mode parameter.

S is a hydrophilic block; H is a hydrophobic block; D is a drug molecule; ( ) denotes that the group is bonded directly or indirectly as a side chain or as part of a side chain group to the adjacent group; and the hyphen, “-” (or sometimes “-”), denotes that each of the adjacent S, H or D are linked either directly to one another or indirectly to one another via a linker, additionally wherein the hydrophilic block comprises a first hydrophilic monomer and the hydrophobic block comprises a first hydrophobic monomer and a second hydrophobic monomer.

Abstract: A pressure sensor for connecting to a detector is provided. The pressure sensor comprises: an optical fibre, having a distal end with a distal plane for sensing pressure, a proximal end for communicating with a patch cord, and an In-fibre Bragg grating (FBG) therebetween; a housing, having a distal aperture, a proximal aperture and a bore therebetween, and sized to accept the optical fibre; an annular ring, forming a flexible seal between said optical fibre and housing at least distal to the FBG and a holder for retaining the housing. The FBG is housed in the housing such that in use, axial strain is transferred to said In-fibre Bragg grating housed within said housing by pressure exerted on the distal plane.

Abstract: An apparatus and method for detecting a skip write in a write operation of a disc drive are provided. The apparatus and method detect occurrence of a sudden change in back emf of a write signal returning from a write element of the disc drive during a write operation. In the preferred embodiments, the apparatus includes a sample module to sample a write signal from the write element and a detect module to detect a sudden change in the back emf. The method preferably includes the steps of providing a write signal to a write element, monitoring a back emf component of the write signal returning from the write element, detecting a sudden change in amplitude of the back emf component, and initiating a rewrite operation if the sudden change exceeds a threshold.

Abstract: The present invention offers an apparatus and associated method to detect a skip write error occurring during a data storage device write process. The capacitance between the read/write head and the disc surface, called the “parasitic capacitance,” is used to determine whether a skip write error has occurred. The amount of parasitic capacitance is determined by monitoring the frequency change at the input of an oscillator of test circuit. A change in the read/write head fly height causes a change in the parasitic capacitance and a corresponding change in the frequency. The parasitic capacitance is compared to a threshold limit to determine whether a skip write error has occurred. The write operation is suspended when a skip write error is detected and a rewrite procedure is instituted.

Abstract: An apparatus and associated method is disclosed to detect a skip write error occurring during a data storage device write process using a voltage standing wave ratio (“VSWR”), determined by monitoring the voltage reflected by the write element. A change in the read/write head fly height is monitored by comparing the instantaneous voltage standing wave ratio to a baseline voltage standing wave ratio. If the read/write head fly height is determined to be outside of a predetermined range, a skip write error is assumed resulting in a suspension of the write operation and the institution of a rewrite procedure.

Abstract: The circuit in accordance with the present invention monitors current signals between the preamplifier and the transducer in a data storage device such as a disc drive utilizing magnetoresistive transducers and/or giant magnetoresistive transducers. The detector circuit includes an amplitude section, a duration section, a frequency section, and an alarm section. The amplitude section has a comparator for detecting when a signal exceeds a predetermined voltage level. The duration section measures the time period that the comparator has an output signal. The frequency section measures the frequency of occurrence of comparator output signals. Each of the sections provides an input to the alarm section which provides an alarm signal condition if the amplitude section magnitude is too high, or the duration times amplitude is too high, or the frequency of occurrences of events is too high.
