Abstract: Low-profile electronic component apparatus and methods of manufacturing and utilizing the same, for use with low-profile mobile devices and other applications. In one embodiment, the mobile device comprises a wireless-enabled smartphone, tablet, or laptop computer, and the component comprises an audio speaker which is recessed into a metallic support element, the latter recessed into the mobile device outer housing. The support element is coated with an insulating material, and conductive traces formed thereon for electrical interface with the contacts of the speaker. When assembled, the installation results in a substantially reduced overall vertical profile, thereby both potentially reducing the overall required thickness of the host device, and creating additional volume within the device housing (such as for other components, and/or enhanced audio response of the speaker) resulting in an additional spacing between the speaker component and any extant antenna assemblies.

Abstract: An adjustable monopole antenna apparatus and methods. In one embodiment, the antenna apparatus is intended for mobile terminals. In an exemplary implementation, there is an adjusting point is provided from which a conductor is branched to an adjusting circuit. The adjusting circuit comprises a switch and alternative reactive elements connected to ground, selectable by the switch. When a reactive element is changed, the electric length and resonance frequency of the radiator change, and the corresponding operating band shifts. If the antenna is configured as a dual-band antenna, the above-mentioned operating band is the lower band. One or more higher operating bands are based e.g. on radiating slots implemented by the same radiator conductor. The operating band of the exemplary embodiment of the antenna below the frequency 1 GHz can be shifted in a wider range than in the corresponding known antennas.

Abstract: Low passive intermodulation (PIM) antenna assemblies and methods for utilizing the same. In one embodiment, the low PIM antenna assembly includes an ultra-wide band quarter wave monopole over ground plane antenna apparatus that operates within a band from 698-5900 MHz. The radiating element is comprised of three (3) features that are separated from one another by one hundred twenty (120°) thus producing a triangular shaped pattern. Such a configuration reduces the nulls by about twenty percent (20%) as compared with similar antenna implementations having flat radiating elements. Moreover, in order to reduce the diameter of the ground plane while simultaneously increasing the electrical length of the ground plane, forming of the ground plane is required. Methods of using the aforementioned low PIM antenna assembly are also disclosed.

Abstract: Techniques for treating a tumor and vaccinating against cancer are described. The techniques include treating the tumor by positioning electrodes over an interface between the tumor and non-tumor tissue and applying sub-microsecond pulsed electric fields. The positioning is facilitated by an imaginary contour line of a threshold value of the electric field. In an example, the imaginary contour line is overlaid over images that include the tumor such that the electrodes are properly positioned over the tumor. The techniques also include vaccinating against cancer by passing sub-microsecond pulsed electric fields through tumor cells of a subject sufficient to cause the tumor cells to express calreticulin on surface membranes. The tumor cells are extracted and introduced with the expressed calreticulin into the subject or another subject, thereby providing a vaccination.

Abstract: This disclosure describes techniques for verifying the identity of a user with a network access control (NAC) device in response to receiving a security assertion request for the user. To verify the identity of a user, an NAC device may, in response to receiving a security assertion request from a user agent executing on a client device, cause the user agent to redirect a session verification request to an NAC client executing on the client device. The NAC client may detect the session verification request, and provide information indicative of a valid network access session for the user to the NAC device. The NAC device may verify the identity of the user based on the information indicative of the valid network access session. In this way, an NAC device may verify the identity of a user without requiring the user to re-authenticate with the NAC device.

Abstract: A subject is inoculated from a disease by exposing a biopsy of a tumor or other abnormal growth to a nanosecond pulsed electric field (nsPEF). A sufficient treatment can be confirmed by detecting calreticulin on the tumor cell membranes, which indicates apoptosis occurring in the tumor cells. Treated tumor cells from the biopsy are then reintroduced into the subject. The calreticulin-exhibiting tumor cells activate the subject's immune system against the tumor, and any other like tumors in the body, and effectively vaccinates the subject against the disease. The treatment can be combined with CD47-blocking antibodies, doxorubicin, CTLA-4-blocking antibodies, and/or PD-1-blocking antibodies. The immune response may be measured at a later time. Specific electrical characteristics of the nsPEF treatments can be based on the type and/or strength of the tumor.

Abstract: In one example, a network device may store health status information specifying a current security status for each of a plurality of authenticated endpoint devices in accordance with an authorization data model. The network device may update the current security status of each of at least two of the plurality of authenticated endpoint devices connected to an enterprise network to indicate that each of the at least two of the plurality of authenticated endpoint devices has a compromised security status, and identify a characteristic common to both of the authenticated endpoint devices having the compromised security status. The network device may interface with one or more policy enforcement devices to quarantine a set of endpoint devices associated with the identified characteristic. The current security status of at least one of the quarantined endpoint devices may indicate that the quarantined endpoint device does not have a compromised security status.
