Abstract: Embodiments detect cyberattack campaigns against multiple cloud tenants by analyzing activity data to find sharing anomalies. Data that appears benign in a single tenant's activities may indicate an attack when the same or similar data is also found for additional tenants. Attack detection may depend on activity time frames, on how similar certain activities of different tenants are to one another, on how unusual it is for different tenants to share an activity, and on other factors. Sharing anomaly analysis may utilize hypergeometric probabilities or other statistical measures. Detection avoidance attempts using digital entity randomization are revealed and thwarted. Authorized vendors may be recognized, mooting anomalousness. Although data from multiple tenants is analyzed together for sharing anomalies while monitoring for attacks, tenant confidentiality and privacy are respected through technical and legal mechanisms. Mitigation is performed in response to an attack indication.

Abstract: In one embodiment, an earpiece system comprising an enhancer is provided. The enhancer is configured to receive an earbud of a speaker and to fit in a user's ear. The enhancer includes a first portion having a first surface that defines a concave crus relief feature. The enhancer further includes a second portion extending from the first portion and forming a sound tunnel having an opening at an end opposite the first portion, and a flexible skirt positioned with the sound tunnel and projecting over the second portion to resiliently seal with the user's ear canal when inserted therein.

Abstract: The invention provides a mechanical hooping press for framing sections of fabric for embroidery machines. The press includes one or more cylindrical assemblies. The preferred embodiment provides at least two pneumatically-operated cylindrical assemblies being operable either in tandem or independently. The device provides a base having a recess, and with a cylindrical assembly positioned directly above the recess. A first ring of an embroidery hoop is placed in the recess and a fabric section is placed upon the first ring. The cylindrical assembly is provided with a hoop disk for detachably retaining the second ring of the embroidery hoop. The second ring is attached to the hoop disk and the hoop disk is then driven toward the recess, eventually driving the second ring into engagement with the first ring, and capturing the fabric section therebetween. The invention also provides a nested hoop disk, and an embroidery hoop especially adapted for use with the mechanical hooper.
