    Abstract: A method of making an inkjet print head may include forming, by sawing with a rotary saw blade, continuous slotted recesses in a first surface of a wafer. The continuous slotted recesses may be arranged in parallel, spaced apart relation, and each continuous slotted recess may extend continuously across the first surface. The method may further include forming discontinuous slotted recesses in a second surface of the wafer to be aligned and coupled in communication with the continuous slotted recesses to define alternating through-wafer channels and slotted recess portions. The method may further include selectively filling the residual slotted recess portions to define through-wafer ink channels.

    Abstract: It is recognized that, because of its unique properties, graphene can serve as an interface with biological cells that communicate by an electrical impulse, or action potential. Responding to a sensed signal can be accomplished by coupling a graphene sensor to a low power digital electronic switch that is activatable by the sensed low power electrical signals. It is further recognized that low power devices such as tunneling diodes and TFETs are suitable for use in such biological applications in conjunction with graphene sensors. While tunneling diodes can be used in diagnostic applications, TFETs, which are three-terminal devices, further permit controlling the voltage on one cell according to signals received by other cells. Thus, by the use of a biological sensor system that includes graphene nanowire sensors coupled to a TFET, charge can be redistributed among different biological cells, potentially with therapeutic effects.

    Abstract: A method and apparatus for multipath switching using per-hop virtual local area network (VLAN) remapping is disclosed. In the method and apparatus, a data packet is forwarded for transmission over one of a first port and a second port. The device identifies a VLAN ID of the data packet as a second VLAN ID and changes the second VLAN ID to a first VLAN ID. Then one or more criteria of a classification set entry for forwarding the data packet over the second port are evaluated. The data packet is forwarded over the second port if the criteria are met and the data packet is associated with the second VLAN ID. Alternatively, the data packet is forwarded over the first port and is associated with the first VLAN ID if a dynamic entry specifies the data packet is to be forwarded over the first port.
