Prior art

To identify the most relevant prior art for US patent 11857333, I will examine the citations listed in the patent. The USPTO provides a Patent Public Search tool for this purpose.

Here's an analysis of relevant prior art citations for US Patent 11857333, based on the patent document itself:

Prior Art References (as cited in US11857333B1):

1. US 7,032,301 B2

   • Full Citation: U.S. Pat. No. 7,032,301
   • Publication/Filing Date: The priority date for US11857333 is listed as 2005-11-04, and US 7,032,301 was granted on April 25, 2006 (information from Google Patents, not explicitly stated in the provided text).
   • Brief Description: This patent describes "Dry physiological recording electrodes." The provided text from US11857333 states that these dry electrodes are advantageous because "they use no gel that can dry out, skin abrasion or cleaning is unnecessary, and the electrode can be applied in a hairy area such as the scalp."
   • Potentially Anticipates Claim(s) under 35 U.S.C. § 102: This reference is cited generally in the description of sensors, specifically electrodes. It anticipates aspects of claims that involve the use of electrodes, particularly for collecting bio-electrical signals like EEG, ECG, and EMG, and the convenience associated with dry electrodes. While it doesn't describe an entire integrated system, it provides a specific component that could be used within the systems described in claims 1, 10, 11, 12, 13, 14, 15, 16, 17, and 20, where physiological sensors (including electrodes) are used.

2. US 5,424,942 A

   • Full Citation: U.S. Pat. No. 5,424,942
   • Publication/Filing Date: The priority date for US11857333 is 2005-11-04. US 5,424,942 was granted on June 13, 1995 (information from Google Patents, not explicitly stated in the provided text).
   • Brief Description: This patent is described as relating to the "ORICATM controller, an extended horizon, adaptive, predictive controller." It is mentioned in the context of system identification models, particularly an Auto-Regressive Moving Average (ARMA) model, used for signal processing to predict the onset of symptoms.
   • Potentially Anticipates Claim(s) under 35 U.S.C. § 102: This reference anticipates aspects of claims involving signal processing and control systems, specifically the use of predictive control or adaptive algorithms to analyze physiological signals and adjust treatment. This would be relevant to claims 1, 10, 11, 12, 13, 14, 15, 16, 17, and 20, particularly where the "electronic component" or "processor" is described as generating a processed signal or making adjustments based on collected signals. The mention of using recursively identified system models and ARMA models to predict symptom onset directly relates to the processing and adjustment steps in these claims.

It's important to note that "potentially anticipates" implies that these prior art references teach certain elements of the claimed inventions. A full anticipation analysis under 35 U.S.C. § 102 would require a detailed claim-by-claim comparison to determine if every element of a given claim is present in a single prior art reference.
