摘要： A computing system helps a person live independently by providing reminders, alerts, and alarms of situations that require the person's attention, notifying another party for emergency or other advice or assistance as necessary. The system receives data from a variety of sensors around the person's environment, developing one or more meaningful composite virtual sensor signals as a function of the data from the physical sensors. Rules operate as a function of the virtual sensor signals to notify the user and/or another party of the situation by way of a smartphone application, cell phone text message, PDA, or other device.

摘要： A system and method for determining when a LED-based position light is nearing its end of life by providing to maintenance personnel visible indication that end of life is approaching. An example system includes a controller, a main LED light, an indicator LED light, a first elapsed time counter, a second elapsed time counter, and an oscillator. The first elapsed time counter recognizes when a first time threshold is exceeded, causing the indicator LED light to flash and triggering the second elapsed time counter to start counting. The second elapsed time counter recognizes when a second time threshold is exceeded, disabling both the indicator LED light and the main LED lights, thereby notifying maintenance personnel that the main LED lights have reached their end of life.

摘要： A stabilized cell suspension is prepared by treating the cell suspension with a solution of a heavy metal compound, which has been aged at pH 6.5-7.5 prior to use to allow a precipitate to form, removing the precipitate from the heavy metal solution, mixing the aged heavy metal solution with the cell suspension to form a first mixture, and mixing the first mixture with a paraformaldehyde solution to form a stabilized cell suspension which is still capable of lysis.

摘要： Disclosed is a high field asymmetric waveform ion mobility spectrometer (FAIMS) having a side-to-side electrode geometry. The FAIMS includes an inner electrode (102) having a length and an outer surface that is curved in a direction transverse to the length. The FAIMS also includes an outer electrode (104) having a length, a channel extending therethrough along at least a portion of the length, and a curved inner surface, a portion of the length of the outer electrode overlapping a portion of the length of the inner electrode so as to provide an analyzer region therebetween. The outer electrode has an ion inlet (114) for introducing ions from a source of ions into the analyzer region and an ion outlet (112) for extracting ions from the analyzer region, the ion inlet and the ion outlet being disposed on opposing sides of the outer electrode. The FAIMS is characterized in that at least one of the inner and outer electrodes is shaped such that a width of the analyzer region in the vicinity of the ion outlet is other than a width of the analyzer region in at least one other region.

摘要： Disclosed are an apparatus and a method for separating ions produced at an electrospray ionization source, based upon the high field mobility properties of the ions. An apparatus according to the instant invention includes a high field asymmetric waveform ion mobility spectrometer (FAIMS) having an analyzer region defined by a space between an inner electrode (32) and an outer electrode (34). In particular, the outer electrode includes an ion inlet (38) for introducing ions into a first portion of analyzer region and an ion outlet (56) for extracting ions from a second portion of the analyzer region. The FAIMS is characterized in that a gas-directing conduit (48) is provided through at least a portion of the inner electrode. In particular, the gas-directing conduit includes an opening at a first end thereof for supporting fluid communication between the gas-directing conduit and the first portion of the analyzer region. The gas-directing conduit is adapted at a second end thereof opposite the first end for supporting fluid communication between a gas source and the gas-directing conduit. The opening is orientated relative to the ion inlet such that gas provided through the gas-directing conduit flows partially outwardly from the analyzer region through the ion inlet, so as to desolvate the ions produced at an ionization source (42, 45) as they are introduced into the analyzer region.
