Abstract: According to an example aspect of the present invention, there is provided a method of managing energy flow and freight transportation within a system. The system can include a plurality of mobile electric assets. The mobile electric assets can be self-propelled vehicles, non-self-propelled vehicles and non-vehicle electric assets. The management includes treating energy flow as a new dimension of a freight transportation system.

Abstract: An optical prism mounting system is described that includes a prism having a flexible insertion tab system. Also described, is a prism holder having an insertion channel, and a method of mounting the prism in a tonometer. The flexible insertion tab system includes a spring tab and a bendable tab; the spring tab is flexed as the prism moves along the channel; the flexible insertion tab system connects with the prism holder and snaps into a locked position at the end of the channel; and the prism and the prism holder can be separated after use by disengaging the flexible insertion tab system. An optical operating range of the optical prism is from about 0 ADC to about 600 ADC, and the maximum time for setting the tonometer is not more than about 150 seconds.

Abstract: Embodiments of the invention relate to a method for transport assignment planning and a system for transport assignment planning. More specifically, embodiments of the method comprise receiving a transport assignment having a start point and an end point, receiving vehicle information about the status of a plurality of electric vehicles in a vehicle fleet. The vehicle information comprises a state of charge for each battery pack of each vehicle. Further, route information is received about a plurality of possible road routes between the start point and the end point. The route information includes information about expected power consumption for each vehicle for each route.

Abstract: A replaceable cornea contactor for an eye examining instrument is made to be discarded after each use. A bendable tab molded on the cornea contactor is deformed by a strain gauge as the cornea contactor is inserted into a cornea contactor holder, and a signal from the strain gauge is used to verify that a previously unused cornea contactor has been inserted into the holder. A microprocessor is programmed to recognize the signal produced by initial deformation of the cornea contactor tab so as to proceed with an eye examination only after receiving the strain gauge signal verifying that a previously unused cornea contactor has been inserted.

Abstract: A tonometer, which uses an applanation prism that reflects light inversely related to an applanated area of the cornea, determines intraocular pressure (IOP) by making initial contact with the cornea, and then pressing the prism against the eye through a predetermined departure range from the initial contact value. The departure can add a predetermined prism pressing force beyond the initial contact value or can increase prism pressing force sufficiently to produce a predetermined increase in the applanated area. From the change in applanated area and prism pressing force required, the microprocessor can be programmed to determine IOP in several ways that do not suffer inaccuracy from variations in tear volume and corneal thickness and curvature in different eyes being examined.

Abstract: A tonometer capable of measuring systolic or ocular pulse pressure (OPP) can be used to examine eyes of a patient to measure whether OPP or ocular blood flow (OBF) is sub-normal to one or both eyes. This can serve as an indication of a possible constriction of blood flow in arteries leading not only to the eyes, but to the brain and other regions above the neck. Any such sub-normal measure can then indicate that further investigation of blood flow in carotid and other arteries is appropriate.
